Merge tag 'topic/devm' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator into HEAD

Provide managed versions of regulator_get() and regulator_bulk_get(),
saving code in error handling and cleanup paths by ensuring that that
the regulators will be automatically unregistered when the device is
unregistered.
