[git pull] drm/vmwgfx fixes for 5.12-rc8

[Dave Airlie]

Hi Zack,

Please make sure to always cc dri-devel and/or Daniel on these so if
I'm away they don't get lost, but also so that they make it into
patchwork for processing.

If you have a chance can you resend it, I'll see if we can process
this out of band and get it to Linus before release.

Dave.
