4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Mark Brown <[email protected]> commit 49a6bb7a1c0963f260e4b0dcc2c0e56ec65a28b2 upstream. The latest workaround for the lockdep interface's not using the second argument of mutex_lock_nested() changed the loop missed locking the last regulator due to a thinko with the loop termination condition exiting one regulator too soon.
