3.16.35-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Vetter <daniel.vetter@xxxxxxxx>
commit 72b9ff0612ad8fc969b910cd00ac16b57a1a9ba4 upstream.
For drm_gem_object_unreference callers are required to hold
dev->struct_mutex, which these paths don't. Enforcing this requirement
has become a bit more strict with
commit ef4c6270bf2867e2f8032e9614d1a8cfc6c71663
