Pull drm fixes from Dave Airlie:
 "The nouveau fixes missed the last pull by a few hours, and we had a
  few arm driver/panel/bridge fixes come in.

  This is possibly a bit more than I'm comfortable sending at this
  stage, but I've looked at each patch, the core + nouveau patches fix
  regressions, and the arm related ones are all around screens turning
  on and working, and are mostly trivial patches, the line count is
  mostly in comments.

  core:
   - fix possible use-after-free

  drm_fb_helper:
   - regression fix to use memcpy_io on bochs' sparc64

  nouveau:
   - format modifiers fixes
   - HDA regression fix
   - turing modesetting race fix

  of:
   - fix a double free

  dbi:
   - fix SPI Type 1 transfer

  mcde:
   - fix screen stability crash

  panel:
   - panel: fix display noise on auo,kd101n80-45na
   - panel: delay HPD checks for boe_nv133fhm_n61

  bridge:
   - bridge: drop connector check in nwl-dsi bridge
   - bridge: set proper bridge type for adv7511"
