UPSTREAM: iommu/amd: Add missing domain type checks
Drivers are supposed to list the domain types they support in their domain_alloc() ops so when we add new domain types, like BLOCKING or SVA, they don't start breaking. This ended up providing an empty UNMANAGED domain when the core code asked for a BLOCKING domain, which happens to be the fallback for drivers that don't support it, but this is completely wrong for SVA. Check for the DMA types AMD supports and reject every other kind. Bug: 254441685 Fixes: 13646796 ("iommu: Add IOMMU SVA domain support") Signed-off-by:Jason Gunthorpe <jgg@nvidia.com> Reviewed-by:
