[PATCH V2 23/29] staging: rts5208: deprecate pci_get_bus_and_slot()

From: Sinan Kaya
Date: Wed Nov 22 2017 - 17:51:28 EST


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.
