First of all, the "segment" name is extremely misleading. PCI spec
assumes everywhere that "segment" is a group of devices sitting
on the same wires (ie primary and secondary buses of the PCI-to-PCI
bridge are *different* segments).
Let's call it "configuration space domain" instead.
Second, why not
- strcpy(dev->dev.bus_id,dev->slot_name);
+ sprintf(dev->dev.bus_id, "%04x:%s", pci_controller_num(dev),
+ dev->slot_name);
?
Ivan.
