No. It also doesn't exist as a 'struct pci_dev'. This caused problems in
the AMD IOMMU driver in the past and I needed to fix that. There I know

Well, I don't think its really meaningless, but we need some way to
communicate the information about device groups to userspace.
I mean the contents of the group descriptor. There are enough 42s in
the kernel, it's better if we can replace a synthetic number with
something meaningful.
