    iommu/mediatek: Include linux/dma-mapping.h · 745b6e74
    Arnd Bergmann authored
    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.
