Unfortunately there was a regression introduced with this patch. The fix
for the regression is tiny and introduced upstream with patch
ed7d78b2da32198ca4c70172e3b63c6b3e2c570b, "drm/vmwgfx: Fix kernel NULL
pointer dereference on older hardware", also CC'd stable.
Please, if possible, make sure both these patches are pushed at the same
time.
