Pull drm fixes from Dave Airlie:
 "Two i915 regressions and one dual-gpu laptop radeon fix"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/radeon: report disconnected for LVDS/eDP with PX if ddc fails
  drm/i915: Cancel vdd off work before suspend
  drm/i915: Ignore SURFLIVE and flip counter when the GPU gets reset
