ERROR: "pci_get_bus_and_slot" [drivers/firmware/edd.ko] undefined!
It should be stubbed, in include/linux/pci.h where all the other PCI
functions are stubbed for the !CONFIG_PCI case.
pci_get_bus_and_slot() shouldn't be used because it fails to work on
systems with multiple domains. pci_get_slot() avoids this problem (and
is much faster too).
But requires you have a bus pointer to hand which is often not the
case. Do we need pci_get_domain_bus_and_slot() ?
Note that EDD has no way of referencing anything but the zero domain
(which is presumably the one which is addressed by I/O ports CF8/CFC on
the BSP.) So in this particular case I would say pci_get_bus_and_slot()
is fine.
