[PATCH v3 0/4] iio: adc: at91: misc driver cleanups

[Alexandru Ardelean]

This whole thing started because the lkp bot haunted me for a while with
this build warning:

>> drivers/iio/adc/at91_adc.c:1439:34: warning: unused variable
>> 'at91_adc_dt_ids' [-Wunused-const-variable]
   static const struct of_device_id at91_adc_dt_ids[] = {
                                    ^
   1 warning generated.

The fix may likely be patch 'iio: adc: at91_adc: add Kconfig dependency
on the OF symbol'; was pointed out by Jonathan.
