8. Obsolete functions

8. Vendor and device identifications

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For the future, let's avoid adding device ids to include/linux/pci_ids.h.



PCI_VENDOR_ID_xxx for vendors, and a hex constant for device ids.



Rationale:  PCI_VENDOR_ID_xxx constants are re-used, but device ids are not.

    Further, device ids are arbitrary hex numbers, normally used only in a

    single location, the pci_device_id table.



9. Obsolete functions

~~~~~~~~~~~~~~~~~~~~~

There are several functions which you might come across when trying to

port an old driver to the new PCI interface.  They are no longer present
