    Subject[PATCH 4.6 089/203] iommu/arm-smmu: Wire up map_sg for arm-smmu-v3
    Date
    4.6-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Jean-Philippe Brucker <jean-philippe.brucker@arm.com>

    commit 9aeb26cfc2abc96be42b9df2d0f2dc5d805084ff upstream.

    The map_sg callback is missing from arm_smmu_ops, but is required by
    iommu.h. Similarly to most other IOMMU drivers, connect it to
    default_iommu_map_sg.
