Merge series "regulator: devres: remove unused device-managed unregister APIs" from Alexandru Ardelean <aardelean@deviqon.com>:

These APIs aren't used anywhere and most-likely exist because of the
general principle of C APIs, where if an API function does an
allocation/registration, it must also have an equivalent
deallocation/deregistration counterpart.

For devm_ functions this isn't all that true (for all cases), as the idea
of these function is to provide an auto-cleanup logic on drivers/system
de-init.

Removing these discourages any weird logic that could be created with
such an API functions.

Alexandru Ardelean (4):
  regulator: devres: remove devm_regulator_unregister_notifier()
    function
  regulator: devres: remove devm_regulator_unregister() function
  regulator: devres: remove
    devm_regulator_bulk_unregister_supply_alias()
  regulator: devres: unexport devm_regulator_unregister_supply_alias()
