Seems like I should post a v4 to update the commit message of the
final patch in the series, but I'm going to leave this the way it is
since the end result is the same. Originally when I wrote the series I
didn't know if the new regulator API changes would be accepted, so the
previous patch did the most cleanup it could do with the old API. ;-)
