Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull DRM fixes from Dave Airlie:
"I was going to leave this until post -rc1 but sysfs fixes broke
hotplug in userspace, so I had to fix it harder, otherwise a set of
pulls from intel, radeon and vmware,
The vmware/ttm changes are bit larger but since its early and they are
unlikely to break anything else I put them in, it lets vmware work
with dri3"
