+Do not add new device or vendor IDs to include/linux/pci_ids.h unless they
+are shared across multiple drivers. You can add private definitions in
+your driver if they're helpful, or just use plain hex constants.

-hex numbers (vendor controlled) and normally used only in a single
-location, the pci_device_id table.
