I think it doesn't matter much.

The PCI_DEVICE and PCI_VDEVICE macro uses are somewhat similar
and are frequently used with PCI_DEVICE_TABLE, so there's some
commonality there.

The checkpatch message could be made --strict/CHK instead of
WARN so most people would never see it.

Of course it could be removed altogether too.  I don't care.
