Oh crap, applied patch to wrong tree. We need to cherry-pick
commit 621bd0f6982badd6483acb191eb7b6226a578328
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Tue Sep 29 09:56:53 2015 +0200
drm: Fix locking for sysfs dpms file
to drm-fixes. Sorry about that screw-up. Dave, can you pls do that one? It
even comes with the needed cc: stable included (since the locking breakage
was done in 4.0, it only surface due to a new warning in 4.3).
