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.
