And I just realized that I've written the same review in the discussion of
the previous patch. Please make sure next time around you address all the
outstanding review, since if you don't the reviewer has to paintstakingly
check _everything_ every time around, which is a massive waste of
everyone's time.
Also can you pls change the subject to include DSI (and drop the MIPI
part, that's just the standard's group and not the standard itself)?
Applies to a few other patches in this series too.
Thanks, Daniel
