Hi Dave and Daniel,

Here goes this week fix.

There was only a small conflict in the multi-cast registers fix,
but that's pretty trivial. Just go with the -gt-next version if
needed on your side.

drm-intel-fixes-2023-01-12:

- Reserve enough fence slot for i915_vma_unbind_vsync (Nirmoy)
- Fix potential use after free (Rob Clark)
- Reset engines twice in case of reset failure (Chris)
- Use multi-cast registers for SVG Unit registers (Gustavo)

Thanks,
Rodrigo.
