The IOMMU subsystem has undergone some changes, including the removal
of iommu_ops from the bus structure. Consequently, the existing domain
allocation interface, which relies on a bus type argument, is no longer
relevant:

struct iommu_domain *iommu_domain_alloc(struct bus_type *bus)

[...]
Applied a few of these to iommu (iommufd/paging-domain-alloc), thanks!

Great, Lu can you please split the remaining by subsystem and try to
get them to go through subsystem trees? Joerg can take the leftovers
at rc6/7 or something like that so we can finish this.

Yes, sure. I guess I need to wait until 6.11-rc1 is out. It's a bit late
in the cycle for the subsystem trees to accept brand new changes.

I think this is enough that Intel and AMD could now assert that dev is
non-null?

Yes.

Thanks,
