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

Pull drm fixes from Dave Airlie:
 "All pretty normal: one TTM oops fix, one radeon, a few intel and a
  vmwgfx fix."

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/ttm: remove unneeded preempt_disable/enable
  ttm: Clear the ttm page allocated from high memory zone correctly
  vmwgfx: return an -EFAULT if copy_to_user() fails
  drm/radeon: fix logic error in atombios_encoders.c
  drm/i915: do not ignore eDP bpc settings from vbt
  drm/i915/sdvo: clean up connectors on intel_sdvo_init() failures
  drm/i915/crt: fix DPMS standby and suspend mode handling
