Here is one of the several errors when compiling.

drivers/iio/adc/max14001.c: In function ‘max14001_probe’:
drivers/iio/adc/max14001.c:315:22: error: implicit declaration of function ‘devm_regmap_init’ [-Wimplicit-function-declaration]
  315 |         st->regmap = devm_regmap_init(dev, NULL, st, &max14001_regmap_config);
      |                      ^~~~~~~~~~~~~~~~
drivers/iio/adc/max14001.c:315:20: error: assignment to ‘struct regmap *’ from ‘int’ makes pointer from integer without a cast [-Wint-conversion]
  315 |         st->regmap = devm_regmap_init(dev, NULL, st, &max14001_regmap_config);
      |                    ^

Funny how I essentially copied the cover letter from the series where I added
missing IIO_TRIGGER_BUFFER entries to Kconfig - to which you didn't require
an example build error :-)

Shall I do a v2 or is this reply enough?

Thanks
