Yup, I butchered this badly. The patch is correct, it also references the
right commits and if those commits would all be in 4.10 it would even
work. But the connector_list locking rework is only in drm-next, which
means it's totally not working :(

Dave, can you pls revert this in drm-fixes and re-apply to drm-next, and
then when you backmerge -fixes into -next make sure git doesn't drop it on
the floor? Or maybe for safety do it the other way round:
- first revert on drm-fixes
- then backmerge
- then reapply to drm-next.

Sorry for this mess ...
-Daniel
