Merge series "regulator: unexport regulator_lock/unlock()" from Michał Mirosław <mirq-linux@rere.qmqm.pl>:

Browse source 
This removes regulator_lock/unlock() calls around
regulator_notifier_call_chain() as they are redundant - drivers
already have to guarantee regulator_dev's existence during the call.

This should make reasoing about the lock easier, as this was the only
use outside regulator core code.

The only client that needed recursive locking from the notifier chain
was drivers/usb/host/ohci-da8xx.c, which responds to over-current
notification by calling regulator_disable().

Michał Mirosław (3):
  regulator: don't require mutex for regulator_notifier_call_chain()
  regulator: remove locking around regulator_notifier_call_chain()
  regulator: unexport regulator_lock/unlock()
