The sysfs interface used to handle PowerVM hotplug events should use the hotplug queue as well. PRRN events will soon be placing many hotplug events on the queue at once and we will need ordinary hotplug events to use the queue as well in order to ensure these events will still be handled and that proper serialization is maintained during the PRRN event.
