Merge tag 'drm-fixes-2020-10-06-1' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "Daniel queued these up last week and I took a long weekend so didn't
  get them out, but fixing the OOB access on get font seems like
  something we should land and it's cc'ed stable as well.

  The other big change is a partial revert for a regression on android
  on the clcd fbdev driver, and one other docs fix.

  fbdev:
   - Re-add FB_ARMCLCD for android
   - Fix global-out-of-bounds read in fbcon_get_font()

  core:
   - Small doc fix"

* tag 'drm-fixes-2020-10-06-1' of git://anongit.freedesktop.org/drm/drm:
  drm: drm_dsc.h: fix a kernel-doc markup
  Partially revert "video: fbdev: amba-clcd: Retire elder CLCD driver"
  fbcon: Fix global-out-of-bounds read in fbcon_get_font()
  Fonts: Support FONT_EXTRA_WORDS macros for built-in fonts
  fbdev, newport_con: Move FONT_EXTRA_WORDS macros into linux/font.h
