I wonder if we should have this as a new separated patch instead of a fixup?
Then when rebasing with autosquash we make sure to put this before the
xe/display patches...

Oded has already started to review the xe-rev1 branch and I'd like
to avoid changes to the patches that are in that branch already.

But this is really small, probably with his ack we can keep as this fixup!
