Other than a few nits below this looks basically OK as a regulator

I suspect you only want the first of these...

Double space here.

Shouldn't this print an error if the power is out of spec (using
dev_err() rather than dev_dbg())?

Using 1 rather than true would be more natural for kernel code.

Normally these should immediately follow the function they annotate.
