Precedence: bulk

Now that fw_devlink=on by default and fw_devlink supports
"power-domains" property, the execution will never get to the point
where driver_deferred_probe_check_state() is called before the supplier
has probed successfully or before deferred probe timeout has expired.

So, delete the call and replace it with -ENODEV.
