This warning triggers on my workstation (with an AMD IOMMU), any ideas?

Argh! When I moved the dma_configure call into iommu_init_device() for
v2 I moved the warning with it, but of course that needs to stay where
it was, *after* the point that ops->probe_device has had a chance to
filter out irrelevant devices. Does this make it behave?

Yes. It works on my end.

Thanks,
