From b714025807366d1925df5c9deccf14bd83e34b02 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 11 May 2017 13:35:51 +0200 Subject: [PATCH] iommu/mediatek: Include linux/dma-mapping.h The mediatek iommu driver relied on an implicit include of dma-mapping.h, but for some reason that is no longer there in 4.12-rc1: drivers/iommu/mtk_iommu_v1.c: In function 'mtk_iommu_domain_finalise': drivers/iommu/mtk_iommu_v1.c:233:16: error: implicit declaration of function 'dma_zalloc_coherent'; did you mean 'debug_dma_alloc_coherent'? [-Werror=implicit-function-declaration] drivers/iommu/mtk_iommu_v1.c: In function 'mtk_iommu_domain_free': drivers/iommu/mtk_iommu_v1.c:265:2: error: implicit declaration of function 'dma_free_coherent'; did you mean 'debug_dma_free_coherent'? [-Werror=implicit-function-declaration] This adds an explicit #include to make it build again.
