From 31dde116cb084bc0042cafe48975ffb7d1a4ae5d Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Thu, 18 Dec 2014 17:13:49 +0000 Subject: [PATCH] arm64: Replace set_arch_dma_coherent_ops with arch_setup_dma_ops Commit a3a60f81ee6f (dma-mapping: replace set_arch_dma_coherent_ops with arch_setup_dma_ops) changes the of_dma_configure() arch dma_ops callback to arch_setup_dma_ops but only the arch/arm code is updated. Subsequent commit 97890ba9289c (dma-mapping: detect and configure IOMMU in of_dma_configure) changes the arch_setup_dma_ops() prototype further to handle iommu. The patch makes the corresponding arm64 changes.
