Pulled to drm-intel-fixes, thanks.

Please note that commits for -rc kernels should mostly be just
fixes. Especially towards the bigger -rc, the rules are about the same
as for stable kernels, i.e. keep it rather conservative. Since GVT-g is
new and isolated, I'm giving you more leeway, but please keep this in
mind going forward.

BR,
Jani.
