SYNOPSIS
struct pci_dev * pci_find_slot(unsigned int bus, unsigned int devfn);
ARGUMENTS
- bus
- number of PCI bus on which desired PCI device resides
- devfn
- encodes number of PCI slot in which the desired PCI device resides
and the logical device number within that slot in case of
multi-function devices.
