Colin Ian King 6b3916435f iommu/omap: Check for failure of a call to omap_iommu_dump_ctx ... [ Upstream commit dee9d154f4 ] It is possible for the call to omap_iommu_dump_ctx to return a negative error number, so check for the failure and return the error number rather than pass the negative value to simple_read_from_buffer.
