Looks good,

As a side note, it appears the struct dma_sgt_handle type is exposed to users of the DMA-API by linux/dma-map-ops.h, but is has no users or functions returning the type explicitly.
This may indicate it's a good idea to move the struct dma_sgt_handle type to drivers/iommu/dma-iommu.c. The decision is left to maintainers :-)
linux/dma-map-ops.h is a helper header for the dma_ops implementations, not for users of the DMA API. sgt_handle, which references dma_sgt_handle is used in kernel/dma/mapping.c
