Great, thanks for testing that patch!

Okay, thats bad, but I think its nothing we should work around right
now. My goal with this work is to have a per-iommu check-device
call-back to bind devices to iommus in the core code.

This will also solve the probe-ordering issue and we are fine again. We
just call check-device then for every device on the bus that has no
iommu already when the iommu is registered and create the links at that
time.
