Merge tag 'iio-fixes-for-4.5b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
Jonathan writes:
Second set of IIO fixes for the 4.5 cycle. These ones are mostly
dependent on patches from the recent merge cycle.
* adc, imu and iio staging drivers
- !HAS_IOMEM dependency fixes
* dht11
- use boottime clock for time measurement to avoid incorrect measurements
due to clock updates.
* lidar
- correct a return value for short i2c transfers.
