Merge tag 'iio-fixes-for-5.2b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus

Jonathan writes:

Second set of IIO fixes for the 5.2 cycle.

* ad7150
  - sense of bit for controlling adaptive vs fixed threshold was flipped.
* adt7316
  - Fix a build issue due to wrong headers for gpio usage.
* lsm6dsx
  - correctly suspend / resume i2c slaves when the host goes to sleep.
* mlx90632
  - relax a compatability check to allow for newer devices.

Also one counters fix

* counter/ftm-quaddec
  - missing dependencies in Kconfig.
