Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
"Nothing too scary, we have one outstanding i915 regression but Daniel
has promised the fix as soon as he's finished testing it a bit.
Fixes for the main x86 drivers:
- radeon: dpm fixes, displayport regression fix
- i915: quirks for backlight regression, edp reboot fix, valleyview
black screen fixes
- nouveau: display port regression fixes, fix for memory reclocking"
* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
