Thanks, applied to drm-misc-next. The patch will appear in -next in a
few weeks.
While applying I had to update a few things:
- checkpatch warning due to indent
- warning for unused variable
- subject, should start with "omapfb:" like other patches touching the
same driver.
I also got a warning because you name differs in your mail and your
s-o-b. "Zhang Qilong" is not the same as "Qilong Zhang".
It would be nice if you for next submission have the same name in both
places.
The patch itself was fine - nice simplifications.
