Hi all,

After merging the drm-misc tree, today's linux-next build (arm

Yes, that patch turned out to be incomplete. Daniel suggested to remove
it from drm-misc for now and I'll address this fully in a larger patch
for 4.4.

Can 96b5d2e807f667320c66f41ddc1c473023a73ab2 from drm-misc-next be 
picked to a -fixes branch? It fixes 3ec5c1579305, which is in 
drm-misc-next and in drm-next.
