I will use Lee's patch as a merge resolution when I merge the gpio
tree (as that is later in my list) from now on. All that has to happen
now is that whichever tree is merged last by Linus (Torvalds) has to
have this same merge resolution applied.
In general, it is better if API changes can be done either as Greg
suggested or with a separate immutable topic branch merged into
whichever trees need it, but it doesn't happen that way very often, so
this is what we generally do.
