pci_find_slot - locate PCI device from a given PCI slot
struct pci_dev * pci_find_slot (unsigned int bus, unsigned int devfn);
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.
Given a PCI bus and slot/function number, the desired PCI device is
located in system global list of PCI devices. If the device is found,
a pointer to its data structure is returned. If no device is found,
NULL is returned.
