post-swap, but crtc_state not used in either. So lgtm.
I wonder if you should go all in and try to rename all the foo_state variables
as new_foo_state and old_foo_state to make sure you didn't miss any uses which
might not agree with your new choice if iterator macro? Eg. if in this
case crtc_state was actually used but you failed notice it you would have
just broken something by using the _new_ iterator.

Doesn't look like this guy actually needs the old state. Not sure why it
was getting passed in. The replacement for plane->state looks correct
nonetheless.
