Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "One drm core fix, one exynos regression fix, two sets of radeon fixes
  (Alex was a bit behind last week), and two i915 fixes.

  Nothing too serious we seem to have calmed down i915 since last week"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/radeon: fix wait in radeon_mn_invalidate_range_start
  drm/radeon: add extra check in radeon_ttm_tt_unpin_userptr
  drm: Exynos: Respect framebuffer pitch for FIMD/Mixer
  drm/i915: Reject the colorkey ioctls for primary and cursor planes
  drm/i915: Skip allocating shadow batch for 0-length batches
  drm/radeon: programm the VCE fw BAR as well
  drm/radeon: always dump the ring content if it's available
  radeon: Do not directly dereference pointers to BIOS area.
  drm/radeon/dpm: fix 120hz handling harder
  drm/edid: set ELD for firmware and debugfs override EDIDs
