0f8d8b3548 iio: dac: ad5592r: destroy mutexes in detach paths 
The locks used here are initialized but never released which causes
resource leaks with mutex debugging enabled. Add missing calls to
mutex_destroy() or use devres if applicable.

a34b88b48a iio: bd79124: Use set_rv and set_multiple_rv 
The new GPIO callbacks 'set_rv' and 'set_multiple_rv' allow returning a
success code to indicate failures when setting GPIO status. Use them to
allow callers to know when things go south.

2a44c3ed80 MAINTAINERS: IIO: Update reviewers for the subsystem 
Lars-Peter has not been active in IIO reviewing for some time. Without
David, Nuno and Andy, along with many others who review IIO patches, I
would not be able to keep up with the rate of change and would have
become a bottleneck to development.

Hence update the MAINTAINERS entry to more accurately reflect reality.
This is not intended to give the 3 of them any more work or to oblige
them to review any particular series, so if there are any series waiting
a long time continue to poke me via the list.

These new functions allow sparse to find failures to release

the mode does not change rather than ensuring we are in direct mode.
A follow up may cleanup the buffer mode claim.

7df3a6eb5c iio: adc: ad7124: Make register naming consistent 
Cleanup definition of register related constants:

 - Use the register and field names exactly as documented in the data
   sheet.
 - Consistently use <regname>_<bitfield> to name a register's bitfield.
 - Drop _MSK definitions and implicit FIELD_PREP calls.
 - Consistent indentation.

7dd17a4e98 iio: adc: ad7124: Remove ability to write filter_low_pass_3db_frequency 
There are several issues with the function that implements writing to
the filter_low_pass_3db_frequency property:

 - The sinc3 factor should be 0.272 not 0.262 (this is fixed for the
   reading side in the previous patch).
 - For freq > 1 the if condition is always true so the sinc4 filter is
   hardly ever chosen.
 - In the nearly always taken if branch the filter is set to sinc3, but
   the frequency is set for sinc4. (And vice versa in the else branch.)

This is broken enough to justify the claim that there isn't any serious
user. Also it it counter-intuitive that setting the 3db frequency
modifies the sample frequency and the filter type.

So drop the ability to write that property.
