Looks good and builds with no warnings.

One of the diffs made me - "oh this looks wrong". But after I looked again
it was right and the resulting code is more readable - so good.

Acked-by: Sam Ravnborg <[email protected]>

Was tempted to just apply to drm-misc-next but will give others the
opportunity to chime in.
