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.
