[Intel-xe] [PATCH 0/1] Don't take a PM ref for vm-less permanent queues

[Daniele Ceraolo Spurio]

VM-less permanent queues exists for the whole lifetime of the driver, so
they can't hold a wakeref. Given that these queues are never
disabled/deregistered and should never hang, we don't expect any G2H
messages outside of the submission flow and therefore we don't need the
extra ref at all as long as the driver makes sure to hold a wakeref when
submitting.
