Please move the parts under the "if" to hotplug.c (something like
hotplug_handler_plug and hotplug_handler_unplug). Also, should this be
moved up to generic code (e.g. bus_add_child/bus_remove_child)?
A NULL link can be a no-op for coldplugged devices, an error for
hotplugged devices, and an assertion failure for hot-unplug.
