NAME

pci_find_subsys - begin or continue searching for a PCI device by vendor/subvendor/device/subdevice id

SYNOPSIS

struct pci_dev * pci_find_subsys (unsigned int vendor, unsigned int device, unsigned int ss_vendor, unsigned int ss_device, const struct pci_dev *from);

ARGUMENTS

vendor: PCI vendor id to match, or PCI_ANY_ID to match all vendor ids
device: PCI device id to match, or PCI_ANY_ID to match all device ids
ss_vendor: PCI subsystem vendor id to match, or PCI_ANY_ID to match all vendor ids
ss_device: PCI subsystem device id to match, or PCI_ANY_ID to match all device ids
from: Previous PCI device found in search, or NULL for new search.

DESCRIPTION

Iterates through the list of known PCI devices. If a PCI device is found with a matching vendor, device, ss_vendor and ss_device, a pointer to its device structure is returned. Otherwise, NULL is returned. A new search is initiated by passing NULL to the from argument. Otherwise if from is not NULL, searches continue from next device on the global list.
