[PULL] drm-intel-next-fixes

[Rodrigo Vivi]

Hi Dave and Daniel,

Here goes our first next-fixes. Please be aware this includes
both drm-intel-next and drm-intel-gt-next.

Also, most of patches from drm-intel-gt-next were accumulated
for not being part of current drm-intel-fixes flow while we
are defining the new split and flow.

So, there are many important fixes for the next and current release
and also for previous stable branches.

Thanks,
Rodrigo.
