    Subject[PATCH V3 18/29] PCI/quirks: 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().

    Extract the domain number from pdev while calling into
    pci_get_domain_bus_and_slot() function.
