Merge tag 'staging-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging / IIO driver updates from Greg KH:
"Here is the large set of staging and IIO driver updates for 5.10-rc1.
Included in here are:
- new IIO drivers
- new IIO driver frameworks
- various IIO driver fixes and updates
- IIO device tree conversions to yaml
- so many minor staging driver coding style cleanups
- most cdev driver moved out of staging
- no staging drivers added or removed
Full details are in the shortlog.
All of these have been in linux-next for a while with no reported
issues"
