Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
"Just regular fixes, bunch from intel, quieting some of the over
zealous power warnings, and the rest just misc.
I've got another pull with the remaining dma-buf bits, since the vmap
bits are in your tree now. I'll send tomorrow just to space things
out a bit."
