Merge tag 'drm-misc-next-2017-01-30' of git://anongit.freedesktop.org/git/drm-misc into drm-next
Another round of -misc stuff:
- Noralf debugfs cleanup cleanup (not yet everything, some more driver
patches awaiting acks).
- More doc work.
- edid/infoframe fixes from Ville.
- misc 1-patch fixes all over, as usual
Noralf needs this for his tinydrm pull request.
