SYNOPSIS
struct pci_dev * pci_get_slot(struct pci_bus * bus, unsigned int devfn);
ARGUMENTS
bus
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.
DESCRIPTION
Given a PCI bus and slot/function number, the desired PCI device is located in the list of
PCI devices. If the device is found, its reference count is increased and this function
returns a pointer to its data structure. The caller must decrement the reference count by
calling pci_dev_put. If no device is found, NULL is returned.
