The comment on the usage of arm_dma_sync_sg_for_cpu(), arm_dma_sync_sg_for_device(), arm_iommu_sync_sg_for_cpu() and arm_iommu_sync_sg_for_device() functions wrongly noted that the "nelems" parameter is the number of sglist entries returned by dma_map_sg(), while this must be the number of entiries passed to dma_map_sg() instead.
