pci_find_device(9)
NAME
pci_find_device - begin or continue searching for a PCI device by
vendor/device id
SYNOPSIS
struct pci_dev * pci_find_device(unsigned int vendor,
unsigned int 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
- 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 and device, a pointer to its device
structure is returned. Otherwise, NULL is returned. A new search is
initiated by passing NULL as the from argument. Otherwise if from is
not NULL, searches continue from next device on the global list.
NOTE
Do not use this function any more; use pci_get_device instead, as the
PCI device returned by this function can disappear at any moment in
time.
