This should return the proper type
Can you please elaborate a bit on "return the proper type"? Did you mean
return iommu_sva_domain instead? That's a wrapper of iommu_domain and
only for iommu internal usage.
If you are exposing special SVA APIs then it is not internal usage
only anymore, so expose the type.
Ah, got you. Thanks for the explanation.
Best regards,
baolu
