struct pci_dev * pci_find_device(unsigned int vendor, unsigned int device, const struct pci_dev * from);
PCI vendor id to match, or PCI_ANY_ID to match all vendor ids
PCI device id to match, or PCI_ANY_ID to match all vendor ids
Previous PCI device found in search, or NULL for new search.
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 to the from argument. Otherwise if from is not null, searches continue from that point.
