Oops!
sc->sc_rid2 = 1;

Resource manager will do it. Device driver for a PnP aware bus will set
resource location for each device under the bus. At that time, the resource
is not allocated and activated. Then a device driver for a child device
will allocate bus resource. rid parameter tells the order of resource you
want to get.
