I may agree with this commit, but:
1. The commit title is incorrect - I don't see "drm/mediatek:" - please look at
the history to find out the right titles for your commits; and
2. The commit description isn't describing anything, you're just repeating the
title: please add a description. What was wrong? What did you fix precisely?
3. There's no Fixes tag. Please add the relevant one.
Regards,
Angelo
