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.
