Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
"Daniel had some fixes queued up, that were delayed, the stolen memory
ones and vga arbiter ones are quite useful, along with his usual bunch
of stuff, nothing for HSW outputs yet.
The one nouveau fix is for a regression I caused with the poweroff stuff"
