	bus->dev = &md->dev;

dev_name(bus->dev) does not describe a controller at all but an 
individual master.

We might as well just change the information as:

snprintf(name, sizeof(name), "master-%d-%d", bus_id, bus->link_id);

you get the system unique ID and controller-relative ID, and you can 
decide to ignore one or the other on different platform.
