nbd c848213af9 (4/6) bcm57xx: switch-core.c/switch-robo.c check for port already registered
This patch prevents switch-robo.c from attempting robo_probe on a port
that is already registered.  robo_probe will adjust kernel reference counts
if it detects a switch on the port.  If this patch wasn't applied, the
wrt350n would hang on reboot, waiting for the network driver reference count
to reach zero indefinitely.
