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
