From 4a4d68fc2657df9a2b4f114081141e2599804586 Mon Sep 17 00:00:00 2001 From: "Wolfram Sang (Renesas)" Date: Wed, 19 Dec 2018 00:12:07 +0100 Subject: ARM: 8818/1: dma-mapping: update comment about handling dma_ops when detaching from IOMMU Update the comment because we don't set the pointer to NULL anymore. Also use the correct pointer name 'dma_ops' instead of 'dma_map_ops'.
