Merge tag 'drm-misc-next-2017-01-09' of git://anongit.freedesktop.org/git/drm-misc into drm-next

Back to regular -misc pulls with reasonable sizes:
- dma_fence error clarification (Chris)
- drm_crtc_from_index helper (Shawn), pile more patches on the m-l to roll
  this out to drivers
- mmu-less support for fbdev helpers from Benjamin
- piles of kerneldoc work
- some polish for crc support from Tomeu and Benjamin
- odd misc stuff all over
