alan: so i believe think its acceptable to make this patch changes independant of where the changes is being used.
From what i recall from our conf-call review last week, this change is needed by patch #7. That said, i am providing
a conditional rb with the condition that this patch needs to be squashed with patch #7 (i.e. the patch titled
"drm/xe/guc: Plumb GuC-capture into dev coredump"):
