Subject[PATCH V3 19/29] PCI/syscall: 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().

Hard-coding the domain value as 0 because the domain information is not
coming from the userspace.
