I don't think it'd be a problem (and if it is, then fix Linux).

If we aren't going to put a correct value in, is zero better than =20
omitting it entirely?

There are other properties in the PCI binding that we don't have, such =20
as slot-names.  I don't see any language in the PCI binding that says =20
one is required but the other isn't.

And shouldn't we be using the PCI express binding (device_type =3D =20
"pciex", or just get rid of it since this isn't real OF)?
