It'd be nice if we could modify _notifier_call_chain() to push the locking out a bit so we don't need to drop the lock before calling the notifier. On the other hand, for anything that isn't memory mapped or GPIO controlled (most regulators are in this category) the cost of the I/O is going to make this a non-issue.
