Subject: ath10k: Fix DMA burst size

A value of zero indicates that 128B is the maximum
DMA request size for read/writes. But PCI cards based
on AR9880 can support 256B, so enable this for
the 10.2 firmware.

Subject: ath10k: Enable RX batching

This feature allows the FW to batch RX indications,
reducing the rate of host interrupt generation, which
in turn reduces CPU load. Currently, this is enabled
only for the 10.2 firmware.

Subject: ath10k: Implement sta_add_debugfs

Add per station debugfs files when a station is added to mac80211's
station list. This helps to group peer specific debugfs entries
altogether. Right now this callback adds support to test aggregation
procedures (addba/addba_resp/delba) manually.

To enable automatic aggregation in target,
echo 0 >/sys/kernel/debug/ieee80211/phyX/netdev:wlanX/
	stations/XX:XX:XX:XX:XX:XX/aggr_mode

For manual mode,
echo 1 >/sys/kernel/debug/ieee80211/phyX/netdev:wlanX/
	stations/XX:XX:XX:XX:XX:XX/aggr_mode

This per-station debugfs entry helps to send addba request in manual

as input.

To send addba,

Subject: ath10k: Fix potential Rx ring corruption

When replenishing Rx buffers driver updates the address of the
buffer and the index of rx buffer in rx ring to the firmware.
Change in order by CPU can cause rx ring corruption. Add memory
barrier before updating rx buffer index to guarantee the order.

This could fix some instances of rx ring corruption due to done
bit in rx attention flag not set.

Subject: ath10k: implement prb tmpl wmi command

New firmware revisions with beacon templates need
probe templates as well because they don't forward
probe requests to host at all.

This is required for new firmware to work with
direct probe requests (notably required by hidden
ssid AP).

Subject: ath10k: fix duration calculation for quiet param

The duty cycle (% of quiet duration) is used to put the device
in quiet mode for the given period. Currently the quiet duration
is wrongly calculated which results in not enabling quiet mode.
Fix the calculation as below

     duration = (period * duty cycle) / 100

Subject: ath10k: prevent fw reg dump spam

Originally the explicit fw register dump was added
to wait_for_target_init because interrupts are
masked early during power_up.

Due to some changes in power_up/reset sequences
sometimes when fw crashed ath10k would print the
dump more than once via hif_stop -> warm_reset ->
wait_for_target_init, possibly with different
values each.

Prevent this by doing the explicit fw register
dump only during power_up instead of
wait_for_target_init.

Subject: ath10k: implement diag data container event

Some firmware revisions may report this event as
part of their diagnostics.

This avoids `unknown event` warnings and adds
tracing for the event.

Subject: ath10k: introduce struct ath10k_skb_rxcb

It doesn't make much sense to share the
ath10k_skb_cb with Rx path. The Rx path doesn't
need to keep any mac80211's data.

Subject: ath10k: implement rx reorder support

New firmware and firmware (qca6174 hw3.0+ and fw
266+) are capable of full aggregation rx
reordering. If it's enabled then Rx is handled via
a new, separate htt event.

The rx ring behaviour is changed a little to
support the new rx scheme. These changes shouldn't
affect qca988x performance.

Subject: ath10k: reset chip before reading chip_id in probe

There are some very rare cases with some hardware
configuration that the device doesn't init quickly
enough in which case reading chip_id yielded 0.
This caused driver to subsequently fail to setup
the device.

Subject: ath10k: add support for qca6174 Rx descriptors

The QCA6174 chip has an extra 4 bytes in
rx_ppdu_end structure which is used in htt_rx_desc
and HTT Rx ring offset setup. This is necessary
for correct Rx for QCA6174 (otherwise Rx
descriptors are overwritten and corrupted).

This means QCA988X will have an extra 4 byte
padding in Rx descriptor layout which is harmless.

Subject: ath10k: add support for qca6174

The QCA6174 in combination with new wmi-tlv firmware is capable of
multi-channel, beamforming, tdls and other features.

This patch just makes it possible to boot these devices and do some basic stuff
like connect to an AP without encryption. Some things may not work or may be
unreliable. New features will be implemented later. This will be addressed
eventually with future patches.

Subject: ath10k: split fw pdev stats parsing

This will make it easier to implement fw stats
parsing for firmware 10.2.

This also renames a few structures for
consistency.

From 20de2229c634382777eb3b8fc54a34be9669ff8a Mon Sep 17 00:00:00 2001
From: Michal Kazior <michal.kazior@tieto.com>

Subject: ath10k: fix 10.2 fw stats parsing

Both 10.2 firmware binaries 10.2-00082-4 and
10.2.4.20 have introduced ABI changes to fw_stats
each. This caused fw_stats to output wrong data.

Define new structures and use them to parse the
statistics correctly.

Subject: ath10k: use idr api for msdu_ids

HTT Tx protocol uses arbitrary host assigned ids
too associate with MSDUs when delivering
completions.

Instead of rolling out own id generation scheme
use the tools provided in kernel.

This should have little to no effect on
performance.

Subject: ath10k: fix dtim period with beacon templates

Firmware supporting beacon templates (i.e. wmi-tlv
for qca6174) doesn't implicitly take dtim period
from the template. Instead it requires vdev param
to be set accordingly.

This fixes dtim period being stuck at 3.

Subject: ath10k: fix nullfunc workaround

The workaround couldn't work correctly because the
802.11 header wasn't properly stripped of QoS Data
bit so it wasn't recognized in the later parts of
tx path as NullFunc frame and ended up in HTT Tx
instead of HTT Mgmt Tx.

New wmi-tlv firmware uses HTT 3.0 protocol which
uses TX_FRM command for management frames (instead
of a dedicated command). To support PMF it is
necessary to provide explicit tailroom.

This patch adds fix to set carrier state off during ndo_open.
Carrier should be set to ON when device is ready to send data.
In case of station/adhoc interface device is able to transfer
data after successful association/join operation.
For AP this would be after bss_active event.

ath9k and ath9k_htc use the variable name "led_blink" to indicate
whether the module parameter "blink" is on. This name is easy to
conflict with other variables, and has caused a compiler error found
by kbuild test bot. The compiler error is as following:

Subject: mwifiex: selectively choose ext_scan support

Some devices do not support extended scan.
This patch adds support to enble ext_scan selectively.
For SD/PCIe interfaces, deefine ext_scan_support as part of
card structure and use it to initialize ext_scan in adapter
during registering device. For USB interfaces, we initialize
ext_scan during register_dev handler.

Subject: wil6210: fix timing of netif_carrier_on indication

netif_carrier_on indication was too late. In case Rx packet received
before netif_carrier_on indication, upper layers could not send
Tx packet back.

The fix is to indicate netif_carrier_on earlier:
for STA, indicate netif_carrier_on when association starts.
for AP/PCP, indicate netif_carrier_on upon starting AP/PCP.

Subject: wil6210: ignore firmware failure to gracefully stop AP

upon cfg80211_stop_ap, a graceful AP shutdown is requested from firmware
followed by firmware reset.
In case graceful request failed, error was returned to cfg80211.

The change is to return success in this scenario, because firmware
reset will anyhow shutdown the AP.

Subject: wil6210: tuning rings size

Tuning rings size for performance optimization.
Increasing Tx ring size, allows buffering more packets for HW, thus
eliminating idle periods which were observed with smaller ring at
high throughput, because HW was fetching packets faster than driver was
filling them into the TX ring. Rx ring was similarly increased to
avoid same problems in Rx.

Subject: brcmfmac: Relax scheduling of msgbuf worker on high throughput.

On every tx the flow worker is triggered. When running high
throughput data this causes an excessive amount of times the worker
gets activated. This patch starts scheduling the worker more relaxed
once outstanding tx has reached a certain depth.

Subject: brcmfmac: prevent possible deadlock on resuming SDIO device.

When the system is resumed a deadlock can occur when DPC gets
entered before resume is complete. This patch fixes this by
properly checking the suspend state outside the claim_host code
block.

Subject: brcmfmac: pass DEAUTH/DISASSOC reason code to user-space

The driver always called cfg80211_disconnected() with reason parameter
set to zero, ie. unknown. However, firmware does provide a valid
802.11 reason code in DEAUTH and DISASSOC event message to the driver.
This patch passes the reason code to cfg80211_disconnected().

Before going in suspend state the watchdog thread needs to put the
device in bus sleep state, which assures it can go in deep-sleep
state during D3 state.

Subject: brcmfmac: SDIO: avoid using bus state for private states.

Each bus driver is maintaing an exported bus state indicating
if upper layers can or cannot send data. SDIO is using this state
also for more private states. This makes handling the states and
state changes complex. This patch minimises the exposed states
and makes SDIO keep track of an internal state where necessary.

Subject: brcmfmac: Reopen netdev queue on bus state data.

During suspend the bus state is put in the down state. When data
is being transmitted during this state then the netdev queue will
be close. This patch will wake the queue on state data if the
queue was closed.

Subject: brcmfmac: do not load firmware when device is already running

In brcmf_usb_probe_cb() the device is checked to determine whether
it is already running firmware. However, when no firmware download
is needed it still continues to request the firmware files. This
is fixed by returning after successful setup.

Subject: brcmfmac: fix nvram processing

The nvram file can hold a key=value combination in which the value
may have spaces, ie. 'RAW1=80 02 fe ff'. The parsing functionality
did not deal with this so it gives an error message:

[621746.311635] brcmfmac: brcmf_nvram_handle_key
	warning: ln=90:col=11: '=' expected, skip invalid key entry

because RAW1=80 is being considerd as key=value pair and it expects
'=' sign after '02' for next key=value pair. This entry can be
completely ignored as firmware does not need it.

Subject: mwifiex: set wiphy params only once

RTS threshold, fragmentation threshold are per device properties.
Setting them on any interface would be reflected for all other
interfaces as well. This patch removes unnesessary command download
per interface.

Subject: mwifiex: do not declare wdev as pointer

wdev is used even after del_virtual_interface handler in cfg80211
in nl80211_post_doit. Since we have freed wdev in handling of
del_virtual_intf, this can result into crash while deleting
interface.
Avoid this be not declaring wdev which part of
mwifiex_private structure but struct wireless_dev type.

FW initialization routine can also be called while changing
virtual interface types.
This patch adds bool parameter "init" to init command routine
so as to differentiate between initialization during driver load
and change virtual interface handler.

Subject: mwifiex: manage virtual interface limits efficiently

Currently interface limits are checked by seeing if bss_mode for
particular priv is set. If bss_mode is not set, interface creation
is allowed. This patch adds framework to initializes maximum virtual
interfaces supported during load time and check current number of
interfaces created agains allowed interface limit during new virtual
interface creation.

Subject: mwifiex: support conversion to any virtual interface type

Currently, we support virtual interface type change from
station<=>adhoc or station <=> p2p client/GO.
This patch adds support to change virtual interface type to
any of the type advertised in interface combinations.

Subject: mwifiex: do not send regulatory update while starting AP

When regulatory domain changes, cfg80211 already issues request
to change regulatory domain to driver via reg_notifier.
There is no need to set regulatory again during start_ap.

Subject: mwifiex: separate function for parsing head and tail IEs

Head & Tail IEs are supposed to be added to beacon and probe response.
This patch adds separate function for parsing head and tail IEs from
cfg80211_beacon_data and sets them to FW.

Subject: mwifiex: add cfg80211 start_radar_detection handler

This patch adds support for cfg80211 start_radar_detection handler.
Upon reception of start_radar_detection, driver prepares radar detect
command to FW.

Delayed work is queued for CAC time which sends radar detection finished
event to cfg80211.

Subject: mwifiex: support for channel report for radar detection

This patch adds support for channel report enabling.
Channel report event happens if radar is detected on specified channel
after driver has issued radar detect command within CAC time.
Driver in turn sends RADAR_DETECTED event to cfg80211 to tell radar was
detected within CAC time.

Subject: mwifiex: channel switch support for mwifiex

This patch adds cfg80211 channel_switch support for mwifiex.
Upon receiving channel switch request, driver would parse channel
switch announcement IE from beacon_data.
If TX is blocked, netdev queues are stopped. IEs from csa_beacon
are then parsed and set to FW.

Subject: mwifiex: 11h handling for AP interface

This patch enables 11h extensions in FW upon detecting DFS
channel in start radar detection/channel switch handlers.
Patch also takes care of disabling 11h when non DFS channels
are to be set during start_ap handler.

Subject: b43: Fix locking FIXME in beacon update top half

b43 has a FIXME about locking in the mac80211 set-beacon-int callback for a long time.
As it turns out there actually is a tiny race window that could result in
a use-after-free bug of the 'current_beacon' memory.
Nobody ever reported this, so it probably never happened.

Fix this by adding a spin lock that protects the current_beacon access.
We must not be in atomic context while accessing hardware (due to SDIO),
so the beacon update bottom half has to clone the skb and release the lock
before writing it to hardware.

Let's all hope that this stops the troll who is trying to submit incorrect
fixes for this issue repeatedly.
And let's hope that I'm not a troll, too, who just hides even more evil code
in an even more complex attempt to fix the issue.

From: Sujith Manoharan <c_manoha@qca.qualcomm.com>
Date: Wed, 28 Jan 2015 17:54:21 +0530
Subject: ath9k: Update QCA953x initvals

This patch disables HW peak detect calibration for
QCA953x, since it is problematic on a few boards.
Instead, manual calibration will be done in the
driver.

Subject: ath9k: Enable manual peak detect calibration

On some AR955x/QCA953x boards, noise floor calibration
gets stuck and the cause is a hardware/BB issue. To fix
this, peak detect calibration in the HW is disabled
and is done in the driver instead. There a few differences
with the calibration routine for older chips like
AR9331.

Subject: b43: AC-PHY: prepare place for developing new PHY support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There are new (not anymore?) Broadcom 802.11ac wireless cards based on
chipsets like BCM4352 and BCM4360. They use a new PHY type (called
simply AC) that will require new specific code.

Subject: ath10k: move wmm param storage to vif

mac80211 already requests WMM per vif but firmware
wasn't able to handle this until now. However new
wmi-tlv firmware for qca6174 is capable of this.

This prepares per-vif WMM param setup.

Subject: ath10k: disable sta keepalive

Firmware revisions providing sta keepalive service
have it enabled by default.

mac80211 already does idle connection polling so
it makes no sense to duplicate this in ath10k.
mac80211 wouldn't even know of the offloaded
keepalive NullFunc frames.

This prevents sending out some extraneous frames
on the air.

During drv_start/drv_stop stress testing in ARM platform,
sometimes target is taking more that 5ms to wake up. Similar
behaviour also noted during driver load and unload iterations.
On such cases, the wakup duration lies between 5-6ms. Hence
increasing pci wakup timeout 10ms to be more safer. With this
changes, able to complete power down/up >100 iterations without
any issues.

Subject: iwlwifi: mvm: always use mac color zero

We don't really need to use different mac colors when adding mac
contexts, because they're not used anywhere.  In fact, the firmware
doesn't accept 255 as a valid color, so we get into a SYSASSERT 0x3401
when we reach that.

Remove the color increment to use always zero and avoid reaching 255.

Subject: iwlwifi: mvm: add beamformer support

VHT Beamformer (BFER) will be used if the peer supports it
and there's a benefit to use it vs. STBC or SISO.
The driver now tells the FW whether BFER and/or STBC are
allowed but the FW will make the decision to use either
or stick to SISO on its own.
BFER is limited to a single remote peer. The driver takes
care of ensuring this to the FW and prioritizes with which
peer BFER will be used.

From 1e9c62fa9158f35dfd73ef6231154710154e6e09 Mon Sep 17 00:00:00 2001

Subject: iwlwifi: mvm: rs: enable forcing single stream Tx decision

In certain testing scenarios we'd like to force a decision
between STBC/BFER/SISO. In the normal scenario this decision
is done by the FW. Enable this option vis debugfs.

Subject: iwlwifi: pcie: prepare the enablement of 31 TFD queues

Some devices have 31 TFD queues. Don't enable it yet since
there are still issues with it, but at least prepare the
code for it. There was a bug in the read pointer assignment,
fix that. Also, move the inline functions to iwl-scd.h which
is the right place.

Subject: iwlwifi: pcie: disable the SCD_BASE_ADDR when we resume from WoWLAN

The base address of the scheduler in the device's memory
(SRAM) comes from two different sources. The periphery
register and the alive notification from the firmware.
We have a check in iwl_pcie_tx_start that ensures that
they are the same.
When we resume from WoWLAN, the firmware may have crashed
for whatever reason. In that case, the whole device may be
reset which means that the periphery register will hold a
meaningless value. When we come to compare
trans_pcie->scd_base_addr (which really holds the value we
had when we loaded the WoWLAN firmware upon suspend) and
the current value of the register, we don't see a match
unsurprisingly.
Trick the check to avoid a loud yet harmless WARN.
Note that when the WoWLAN has crashed, we will see that
in iwl_trans_pcie_d3_resume which will let the op_mode
know. Once the op_mode is informed that the WowLAN firmware
has crashed, it can't do much besides resetting the whole
device.

Subject: iwlwifi: mvm: ignore stale TDLS ch-switch responses

During out-of-channel activities (e.g. scan) TDLS ch-switch responses from
a peer are kept in FW. These packets arrive only after the out-of-channel
activity is complete, which can be in the order of several seconds.

Since TDLS ch-sw has no dialog-token-like mechanism for distinguishing
sessions, use the GP2 time of the incoming ch-switch response to discern
validity. For this purpose record the GP2 time of an outgoing TDLS ch-sw
request and compare to the Rx time of the ch-sw response.
The methods works in practice since the GP2 time of FW-deferred Rx is
accurate and contains the real Rx timestamp.

Subject: iwlwifi: mvm: enable watchdog on Tx queues for mvm

This watchdog allows to monitor the transmit queues. When a
queue doesn't progress for a too long time, a timer fires
and then, debug data can be collected.
This watchdog has never been enabled on dvm controlled
devices, so don't enable it there.
In order to have it running on mvm controlled devices, we
need to fix a small issue in the transport layer: mvm
controlled devices use the shadow registers optimization.
In this case, the watchdog wasn't running at all, even if
enabled by the module parameter. Fix that on the way.

Subject: iwlwifi: allow to define the stuck queue timer per queue

Different queue can have different behavior. While it can be
unacceptable for a certain queue to be stuck for 2 seconds
(e.g. the command queue), it can happen that another queue
will stay stuck for even longer (a queue servicing a power
saving client in GO).
The op_mode can even make the timeout be a function of the
listen interval.

Subject: iwlwifi: mvm: Fix a few EBS error handling bugs

Last EBS status wasn't set to success in the initialization, which
caused the first scan to be without EBS. Fix that.

When EBS is not enabled by the driver, the FW still sends ebs_status success,
which can override EBS failure state. Consider only EBS failures, to avoid
such override. Last_ebs_success is set back to true upon disconnection.

Last_ebs_success wasn't set in umac scan abort flow, fix that too.

coded to save CPU time by not doing the calculation every interrupt. This

The firmware supplies two kinds of packets via the RX mechanism. Besides the
normal data received over the air, these packets may contain bluetooth status
and other information. The present code fails to detect which kind of
information was received.

Subject: mwifiex: fix memory leak in mwifiex_send_processed_packet()

Memory is leaked after downloading already processed packet. This
patch fixes the problem by freeing returned skb. Other transmit
paths don't have this problem.

Subject: mwifiex: fix NULL packet downloading issues

This patch makes sure that skb is freed after downloading
NULL packet in error cases. Also, USB chipsets return
-EINPROGRESS after downloading packets, they are freed in
USB completion handler later. We will add missing change
to set tx_lock_flag for USB which blocks further packets.

Subject: mwifiex: disable UAPSD mode when AP starts

When AP is started, firmware exits power save mode. This
means power save manager of AP takes priority over station.
Firmware stop sending periodic AWAKE events to host.

We may have UAPSD enabled on station which buffers data
packets until AWAKE event from firmware. Data path is
unnecessarily blocked in this case. This patch disables
UAPSD mode to reenable transmit data path.

Subject: ath9k: Fix wow init/deinit

Registering the card as a wakeup source needs to
be done once, during initialization. When the WOW
configuration changes, the card's status as wakeup
source needs to be changed too and this is done
via the set_wakeup() callback. Also, make sure
the device is removed properly using ath9k_deinit_wow().

The various variables tracking bmiss interrupts
are not really used anywhere except in a debug

purpose.

Subject: ath9k: Remove incorrect register macros

These macros are applicable to pre-AR9003 chips
and the addresses are different for the AR9003
family. Since they are unused anyway, remove them.

Subject: ath9k: Fix max pattern check

Since the maximum number of configurable patterns
is chip-specific, use the HW capability instead
of a fixed value for checking if a free pattern
slot is available.

to be used. This is no more necessary, as firmware supports
multiple destinations

Subject: ath10k: prevent setting wrong key idx for station

Ath10k driver sets wrong default key idx that results in
sending unicast frames with multicast key.

The reason for this behavior is that cached broadcast key
is installed for station MAC address on association. After
dot1x completes, unicast key is installed for station
MAC address. Default key idx is set to broadcast key id when
driver tries to send broadcast frame. This causes firmware
to use broadcast key id to transmit unicast frames to stations.

Used TX_USAGE flag to set default key for stations.

Added callback for setting unicast default idx which will be
invoked on every default key idx configuration.

To prevent this make sure to release ar->data_lock
while calling to ath10k_wmi_beacon_send_ref_nowait().

Subject: ath10k: Use TX cksum offload only for CHECKSUM_PARTIAL

Otherwise ath10k will just checksum everything even if it did not
go through the TCP/IP stack (for example bridged frames). In the worst
case this could mean recreating the checksum for incorrect data.

Subject: ath10k: add log level configuration for fw_dbglog

Introduce an optional log level configuration for the existing debugfs fw_dbglog file. It
allows users to configure the desired log level for firmware dbglog messages.

To configure log level as WARN:

echo 0xffffffff  2 > /sys/kernel/debug/ieee80211/phy0/ath10k/fw_dbglog

The values are:

VERBOSE		0
INFO		1
WARN		2
ERR		3

The 3.2 revision has a different target BMI

the chip_id rev being on the supported list
already).

Subject: rtlwifi: rtl8192ee: Fix handling of new style descriptors

The hardware and firmware for the RTL8192EE utilize a FIFO list of
descriptors. There were some problems with the initial implementation.
The worst of these failed to detect that the FIFO was becoming full,
which led to the device needing to be power cycled. As this condition
is not relevant to most of the devices supported by rtlwifi, a callback
routine was added to detect this situation. This patch implements the
necessary changes in the pci handler, and the linkage into the appropriate
rtl8192ee routine.

Subject: rtlwifi: rtl8192ee: Fix problems with calculating free space in FIFO

This driver utilizes a FIFO buffer for RX descriptors. There are four places
in the code where it calculates the number of free slots. Several of those
locations do the calculation incorrectly. To fix these and to prevent future
mistakes, a common inline routine is created.

Newer chips like WB222, WB335 support more than
8 user-configurable patterns. This patch adds
support for it by setting up the correct HW
registers.

Subject: ath9k: Fix issues with WoW enable

This patch addresses several issues with the
ath9k_hw_wow_enable() routine:

* The usage of set/clr variables is removed. Writing
  the required values to registers is cleaner.

* The shift value of 28 for the contention window field
  in AR_WOW_PATTERN is incorrect, change it to 27.

* Disabling Keep Alive needs to be done based on the
  LINK_CHANGE option. This is done unconditionally now,
  fix this.

* The workaround for the D1/D3 issue is required only
  for AR9462.

* The bitfield for enabling pattern matching for packets
  less than 256 bytes has expanded for new chips, handle
  this accordingly.

* General cleanup.

Subject: ath5k: fix spontaneus AR5312 freezes

Sometimes while CPU have some load and ath5k doing the wireless
interface reset the whole WiSoC completely freezes. Set of tests shows
that using atomic delay function while we wait interface reset helps to
avoid such freezes.

The easiest way to reproduce this issue: create a station interface,
start continous scan with wpa_supplicant and load CPU by something. Or
just create multiple station interfaces and put them all in continous
scan.

This patch partially reverts the commit 1846ac3dbec0 ("ath5k: Use
usleep_range where possible"), which replaces initial udelay()
by usleep_range().

I do not know actual source of this issue, but all looks like that HW
freeze is caused by transaction on internal SoC bus, while wireless
block is in reset state.

Also I should note that I do not know how many chips are affected, but I
did not see this issue with chips, other than AR5312.

Subject: orinoco: orinoco_pci use msecs_to_jiffies for conversion

This is only an API consolidation and should make things more readable
it replaces var * HZ / 1000 by msecs_to_jiffies(var).

Subject: cw1200: Delete an unnecessary check before the function call
 "release_firmware"

The release_firmware() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

Subject: cw1200: Less function calls in cw1200_load_firmware_cw1200() after
 error detection

The functions kfree() and release_firmware() were called in a few cases
by the cw1200_load_firmware_cw1200() function during error handling even if
the passed variables contained still a null pointer.

Corresponding implementation details could be improved by adjustments for
jump targets.
