Merge tag 'drm-misc-next-2017-10-05' of git://anongit.freedesktop.org/git/drm-misc into drm-next

More drm-misc for 4.15:

Cross-subsystem Changes:
- bunch more simple outreachy patches (Meghana Madhyastha, Aishwarya
  Pant, Haneen Mohammed)
- Quite a pile of static checker/cocci/spelling fixups all over.
- Final driver patches+core cleanup of Noralf's new drm_gem_fb_create
  helper.

Core Changes:
- legacy DPMS docs improved
- add dri-devel m-l to fbdev to catch people who try to fix
  fbcon-on-kms bugs in the wrong place

Driver Changes:
- vc4: prep for dsi panels (Eric)
