[PATCH v2 0/5] iio: adc: use devm_regulator_get_enable_read_voltage round 1

[David Lechner]

Following up from [1], this is the first round of patches to convert the
ADC drivers to use devm_regulator_get_enable_read_voltage().

Some of these are trivial but some aren't so I'm breaking them up into
smaller series to spread out the review load (and my work load).

Changes in v2:
- avoid else in return value checks
- fix unintentional changes in behavior
- use macros instead of comments for internal reference voltage
- Link to v1: https://lore.kernel.org/r/20240531-iio-adc-ref-supply-refactor-v1-0-4b313c0615ad@xxxxxxxxxxxx
