Merge tag 'drm-fixes-for-v4.10-rc7' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
"Another fixes pull for v4.10, it's a bit big due to the backport of
the VMA fixes for i915 that should fix the oops on shutdown problems
that you've worked around.
There are also two drm core connector registration fixes, a bunch of
nouveau regression fixes and two AMD fixes"
