PCI_GET_SLOT(9)                        Hardware Interfaces                        PCI_GET_SLOT(9)



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.
