Subject[PATCH V4 05/26] agp: nvidia: deprecate pci_get_bus_and_slot()
Date
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.

Getting ready to remove pci_get_bus_and_slot() function in favor of
pci_get_domain_bus_and_slot().

Replace pci_get_bus_and_slot() with pci_get_domain_bus_and_slot()
and extract the domain number from struct pci_dev.
