From 56fa2ece881348d314800b858581f2ae950f8e20 Mon Sep 17 00:00:00 2001 From: "Jon Medhurst (Tixy)" Date: Fri, 17 Jul 2015 12:01:29 +0100 Subject: [PATCH] staging: ion: ion_cma_heap: Don't directly use dma_common_get_sgtable Use dma_get_sgtable rather than dma_common_get_sgtable so a device's dma_ops aren't bypassed. This is essential in situations where a device uses an IOMMU and the physical memory is not contiguous (as the common function assumes).
