FYI, I fixed the checkpatch issue when I applied at media_stage:

	https://git.linuxtv.org/media_stage.git/commit/?id=8a5457b7c7c3b6aa1789b18bbaff9b6a99d74caa

Ok, I could have instead replied to Tsuchiya instead, but, as Andy
pointed, those patches solved longstanding issues at the atomisp
driver. So, I just went ahead and cleaned up the issue ;-)

Yeah, agreed. The best is to run checkpatch and save some time from
the maintainers.

In any case, as Andy pointed out, this driver still requires major
cleanups everywhere. Yet, our current focus is to make it work with
standard V4L2 apps.
