Probably something like this:

static inline int pci_name_bus(char *name, struct pci_bus *bus)
{
        if (pci_domain_nr(bus) < 256) {
                sprintf(name, "%02x", bus->number);
        } else {
                sprintf(name, "%04x:%02x", pci_domain_nr(bus), bus->number);
        }
        return 0;
}
