You should be able to bin all your dpms implementations too, at least if
you switch to the new enable/disable hooks for crtc/encoder.
prepare/commit/dpms are all depcrecated (for both crtc and encoder) and
shouldn't be needed any more.  Same with crtc_funcs->mode_set.

But yeah the functional change should be all there is, if it still works
you're all set.
