Subject[PATCH V2 23/29] staging: rts5208: 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().

Remove unused rtsx_read_pci_cfg_byte() function.
