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.

Or use drm-misc-fixes train, usually it leaves on schedul :-) -Daniel

vmwgfx fixes for regressions in 5.12

Here's a set of 3 patches fixing ugly regressions in the vmwgfx driver. We broke lock initialization code and ended up using spinlocks before initialization breaking lockdep. Also there was a bit of a fallout from drm changes which made the core validate that unreferenced buffers have been unpinned. vmwgfx pinning code predates a lot of the core drm and wasn't written to account for those semantics. Fortunately changes required to fix it are not too intrusive. The changes have been validated by our internal ci.
