I think its more something like iommu->iommu->dev.

Without actually running a driver and getting some debug info, I'll just
say that my example compiled, the amd_iommu structure points to a pci_dev which contains a device, and the two possibilities are likely equivalent.

I'll vet that, of course, but working under the assumption that they are equivalent, the question becomes, do you have a preference?
