Well, this doesn't exist in our drm-tip baseline, so it would be good
if this patch is a fixup! to whatever patch is adding this back here.

Take a look to the Jani series I just pushed:

https://lists.freedesktop.org/archives/intel-xe/2023-April/002000.html

I believe you should make this series on something more like that.
so on a next step I run a rebase --autosquash and we get cleaner patches.

Also, I believe this series here might conflict with that, so I'm
afraid you will have to rebase it anyway. Sorry about that...
