Merge series "regulator: fix deadlock vs memory reclaim" from Michał Mirosław <mirq-linux@rere.qmqm.pl>:

For systems that have eg. eMMC storage using voltage regulator, memory
reclaim path might call back into regulator subsystem. This means we
have to make sure no allocations happen with a regulator or regulator
list locked.

After this series I see no more lockdep complaints on my test system,
but please review and test further.

First four patches move allocations out of locked regions, next three
came as a drive-by cleanups.
