I think your driver broke in v6.0 ?

commit 57365a04c921 ("iommu: Move bus setup to IOMMU device registration")

Interesting, thank you for the information. Last time I have checked against: https://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git/log/?h=for-linus... which doesn't seem to have that commit yet...

Anyway, I will try to get to it, but I am sure when exactly, I hope it will be next week.
