Commit <17de3f5fdd35> ("iommu: Retire bus ops") removes iommu ops from
the bus structure. The iommu subsystem no longer relies on bus for
operations. So iommu_domain_alloc() interface is no longer relevant.
A new helper named iommu_paging_domain_alloc() was introduced in the
iommu subsystem as a replacement of iommu_domain_alloc(). This helper
relies on the device for IOMMU API use instead of the bus.
The replacement work started from this series:
https://lore.kernel.org/linux-iommu/20240610085555.88197-1-baolu.lu@xxxxxxxxxxxxxxx/
Several patches have already been merged into the mainline kernel, but
we've decided to route all remaining ones through the subsystem tree.
Change log:
v2:
- Patch 3/3: use dev->dev.parent as the input for
iommu_paging_domain_alloc(), suggested by Thierry Reding.
