I'd split this up a bit differently, with a patch per function. But then
including in that patch the prototype change (at least for the
drm-internal ones that aren't used by drivers). This way reviewers don't
have to check the entire series to make sure that we drop the now
pointeless return value from the implementation of these functions.
I guess you could also just squash this function into the last one, it's a
fairly small patch still.
