Hi,
I've backported this two commits: f9e96bf19054 drm/vmwgfx: Fix possible invalid drm gem put calls 91398b413d03 drm/vmwgfx: Keep a gem reference to user bos in surfaces
They both fixes a950b989ea29 ("drm/vmwgfx: Do not drop the reference to the handle too soon") which has been backported to v6.1.x branch as 0a127ac97240
There was a lot of conflicts, and as I'm not familiar with the vmwgfx driver, it's better to review and test them. I've run a short test, and it worked, but that's certainly not enough.
Thanks,
