6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Markus Burri <markus.burri@xxxxxx>
commit 21d7241faf406e8aee3ce348451cc362d5db6a02 upstream.
Channel configuration doesn't work as expected.
For FIELD_PREP the bit mask is needed and not the bit number.
Fixes: 874bbd1219c7 ("iio: adc: ad7192: Use bitfield access macros")
