to be handled by platform and generic code, not individual drivers.
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
