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

Daniel writes:

" Nothing too major:
- A few fixes around the edid handling from Jani, also fixing a regression
  in 3.5 due to us using gmbus by default.
- Fixup hsw uncached pte flags.
- Fix suspend/resume crash when using hw contexts, from Ben.
- Try to tune gpu turbo a bit better, seems to help with some oddball
  power regressions."

* 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel:
  drm/i915: use hsw rps tuning values everywhere on gen6+
  drm/i915: fall back to bit-banging if GMBUS fails in CRT EDID reads
  drm/i915: extract connector update from intel_ddc_get_modes() for reuse
  drm/i915: fix hsw uncached pte
  drm/i915/contexts: fix list corruption
  drm/i915: fix EDID memory leak in SDVO
