Merge tag 'iio-fixes-for-4.17a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
Jonathan writes:
First round of IIO fixes for the 4.17 cycle.
* core
- fix up some issues with overflow etc around wrong types
for some fo the kfifo handling functions. Seems unlikely
this would be triggered in reality but the fixes are simple
so let's tidy them up. Second patch deals with checking
the userspace value passed for length for potential overflow.
* ad7793
- Catch up with changes to the ad_sigma_delta core and use
read_raw / write_raw iwth IIO_CHAN_INFO_SAMP_FEW to handle
sampling frequency control.
* at91-sama5d2
- Channel config for differential channels was completely broken.
- Missing Kconfig dependency for buffer support.
* hid-sensor
- Fix an issue with powering up after resume due to wrong reference
counting.
* stm32-dfsdm
- Fix an issue with second writes of the oversampling settings
failing.
- Fix an issue with the sample rate being set to half of requested
value when particular clock source is used.
