NAME
pci_get_slot - locate PCI device for a given PCI slot
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.
