As I'm not the PCI maintainer anymore, I'll let Bjorn decide about this.

But, your original patch series isn't ok, we don't want to export the
pci vendor/device ids to userspace, that isn't the job of the kernel to
do so.  If we should be exporting the pci class and config structures or
not is Bjorn's decision.
