10 unsigned int devfn);

13 bus
14 PCI bus on which desired PCI device resides
15
16 devfn
17 encodes number of PCI slot in which the desired PCI device resides
18 and the logical device number within that slot in case of
19 multi-function devices.

22 Given a PCI bus and slot/function number, the desired PCI device is
23 located in the list of PCI devices. If the device is found, its
24 reference count is increased and this function returns a pointer to its
25 data structure. The caller must decrement the reference count by
26 calling pci_dev_put. If no device is found, NULL is returned.
