parisc: Check the return value of ioremap() in lba_driver_probe()
The function ioremap() in lba_driver_probe() can fail, so its return value should be checked. Fixes: 4bdc0d676a643 ("remove ioremap_nocache and devm_ioremap_nocache") Reported-by: Hacash Robot <hacashRobot@santino.com> Signed-off-by: William Dean <williamsukatube@gmail.com> Signed-off-by: Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org> # v5.6+
