Hi all, this series fixes a rather gross layering violation in videobuf2, which pokes into arm DMA mapping internals to get a DMA address for memory that does not have a page structure, and to do so fixes up the dma_map_resource implementation to not provide a somewhat dangerous default and improve the error handling.
Changes since v1: - don't apply bus offsets in dma_direct_map_resource _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
