[PATCH 0/6] iio: use devm_regulator_get_enable_read_voltage round 3

[David Lechner]

This is the third round of patches to convert IIO drivers to use the
new devm_regulator_get_enable_read_voltage() helper function.

This time, we are converting some Microchip drivers. These weren't as
trivial as some other drivers because of nested functions that need
to know info about the reference voltage, but for the most part, should
be fairly straightforward. And there is a bonus to remove a remove()
callback in one of the drivers.
