pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as where a PCI device is present. This restricts the device drivers to be reused for other domain numbers.
Use pci_get_domain_bus_and_slot() with a domain number of 0 where we can't extract the domain number. Other places, use the actual domain number from the device.
