Subject: [PATCH 0/7] iio: adc: clean up claims on direct mode in ad7* drivers

This set looks at the ad7* drivers and migrates them to use the 
iio helper functions iio_device_claim|release_direct_mode(). 

The first three (7266,7791,7793) were not already holding a lock on
direct mode, so this will be a change in behavior for those drivers.

The last four (7476,7887,7923,799x) were already locking so these
are migrations to the claim/release helper functions.

Worth noting: This does not clean up all mlock (ab-)uses in ad799x. 
This driver is still using mlock in a few other places not associated
with locking down direct mode. 

Alison Schofield (7):
  iio: adc: ad7266: claim direct mode during sensor read
  iio: adc: ad7791: claim direct mode when writing frequency
  iio: adc: ad7793: claim direct mode when writing frequency
  iio: adc: ad7476: use iio helper function to guarantee direct mode
  iio: adc: ad7887: use iio helper function to guarantee direct mode
  iio: adc: ad7923: use iio helper function to guarantee direct mode
  iio: adc: ad799x: use iio helper function to guarantee direct mode
