[PATCH 5.10 0/1] iommu/amd: Prepare for multiple DMA domain types

[Daniil Dulov]

Svacer reports possible dereference of a NULL-pointer in 
amd_iommu_probe_finalize(). The problem is present in 5.10 stable release
and can be fixed by the following upstream patch. In order to apply this
patch, the incoming changes had to be manually accepted. This action was
necessary due to some differences in the code of amd_iommu_probe_finalize()
of the upstream version and 5.10 version of the kernel.
