pci_find_device_reverse — begin or continue searching for a PCI device by vendor/device id
struct pci_dev * pci_find_device_reverse ( | unsigned int | vendor, |
| unsigned int | device, | |
| const struct pci_dev * | from); |
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.
Iterates through the list of known PCI devices in the reverse order of
pci_find_device.
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 previous device
on the global list.
