Merge tag 'drm-intel-fixes-2013-08-08' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes 

Daniel writes:
A few bugfixes for serious stuff and regressions. Highlight is the
reinstated hack to keep the i915 backlight on when running on an optimus
machine, this prevents black screens especially with some radeon muxed
platforms. And the patch to quiet dmesg on Linus' old mac mini ;-)

* tag 'drm-intel-fixes-2013-08-08' of git://people.freedesktop.org/~danvet/drm-intel:
  drm/i915: do not disable backlight on vgaswitcheroo switch off
  drm/i915: Don't call encoder's get_config unless encoder is active
  drm/i915: avoid brightness overflow when doing scale
  drm/i915: update last_vblank when disabling the power well
  drm/i915: fix gen4 digital port hotplug definitions
