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.
