Sorry for slow reply. Shouldn't that be regulator_disable() ?
Indeed it should be. In fact I think this probably explains
the failure I saw the other day, trying to go from 3.3V on one
chip down to 1.8V, where it failed (reasons unknown so far)
but the cleanup left vcc_aux active. Got patch? :)
I meant this one to be a patch/RFC ... so you could see how I
thought those issues should be addressed, vs the less general
patches you sent the other day. Actually merging this one
runs into that annoying regulator framework isssue on most
systems.

The linker is not happy with built-in code trying to call functions in a module
directly.
