Merge tag 'topic/drm-misc-2016-07-14' of git://anongit.freedesktop.org/drm-intel into drm-next

I recovered dri-devel backlog from my vacation, more misc stuff:
- of_put_node fixes from Peter Chen (not all yet)
- more patches from Gustavo to use kms-native drm_crtc_vblank_* funcs
- docs sphinxification from Lukas Wunner
- bunch of fixes all over from Dan Carpenter
- more follow up work from Chris register/unregister rework in various
  places
- vgem dma-buf export (for writing testcases)
- small things all over from tons of different people
