Merge branch 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes

Daniel writes:
"- some register magic to fix hsw crw (Paulo&Ben)
- fix backlight destruction for cpu edp (Jani)
- fix gen ch7xxx dvo ->get_hw_state
- fixup the plane->pipe fixup code, the broken version massively angers
  the modeset sanity checks
- kill pipe A quirk for i855gm, otherwise I get a black screen with the
  above patch
- fixup for gem_get_page helper (Chris)
- fixup guardband clipping w/a (Ken), without this mesa master can erronously
  drop vertices on snb, mesa 9.0 has the optimization reverted
- another pageflip vs. modeset fix
- kill bogus BUG_ON which broke ums+gem from Willy Tarreau (gasp, people
  are still using this!)"

* 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel:
  drm/i915: fix non-DP-D eDP backlight cleanup and module reload
  drm/i915: HSW CRW stability magic
  drm/i915/dvo-ch7xxx: fix get_hw_state
  drm/i915: fixup the plane->pipe fixup code
  drm/i915: rip out the pipe A quirk for i855gm
  drm/i915: disable wc gtt pte mappings on gen2
  drm/i915: fixup i915_gem_object_get_page inline helper
  drm/i915: Disallow preallocation of requests
  drm/i915: Set guardband clipping workaround bit in the right register.
  drm/i915: paper over a pipe-enable vs pageflip race
  drm/i915: remove useless BUG_ON which caused a regression in 3.5.
