There is no point in keeping unused IDs around. Yes and that's exactly the reason why removing unused IDs will be a problem. Let's take an exemple: some patch adds PCI_DEVICE_ID_ARECA_1682 after PCI_DEVICE_ID_ARECA_1681 in pci_ids.h in the mainline. That patch needs to be backported and it conflicts with PCI_VENDOR_ID_S2IO which is not anymore in the mainline but is still in stable. Christophe
