| |
4.4-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.
