Merge tag 'topic/drm-misc-2015-12-14' of git://anongit.freedesktop.org/drm-intel into drm-next

Browse Source 
Last (very likely at least) drm-misc pull for 4.5. 3 big things:
- piles of docs for kms vtables.
- drm.debug dmesg output prettification from Ville (i915 parts are for 4.6
  I think)
- connector mode probing/validating/merging cleanup from Ville.

[airlied : fix drm_encoder_init conflict.]

* tag 'topic/drm-misc-2015-12-14' of git://anongit.freedesktop.org/drm-intel: (43 commits)
