Merge tag 'iio-fixes-for-4.20a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
Jonathan writes:
First set of IIO fixes for the 4.20 cycle.
* st_magn
- Avoid an ordering issue that lead to large numbers of unhandled
interrupts whilst enabling buffered capture.
* hid-sensors
- Fix a long running problem with signed values reading wrong from
sysfs on these sensors. It appears people were only using the
buffered interface. These typically occur in laptops so chances
are everyone was using the sensor-proxy which will use the buffered
interface by default.
* tag 'iio-fixes-for-4.20a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio:
iio/hid-sensors: Fix IIO_CHAN_INFO_RAW returning wrong values for signed numbers
iio:st_magn: Fix enable device after trigger
