Shut off the long standing linux/drivers/pci/search.c:144: warning: 'pci_find_device' is deprecated (declared at linux/drivers/pci/search.c:136) linux/drivers/pci/search.c:144: warning: 'pci_find_device' is deprecated (declared at linux/drivers/pci/search.c:136) warnings that appear on every build when CONFIG_PCI_LEGACY is enabled. gcc warns for the use in EXPORT_SYMBOL I moved these to a separate file and disabled the warning in the Makefile for that file.

/**

* pci_find_device - begin or continue searching for a PCI device by vendor/device id
|
|
* @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. 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.
