Date: Thu, 18 May 2017 15:13:57 +0200 From: Arnd Bergmann <arnd@...db.de> To: Joerg Roedel <jroedel@...e.de> Cc: Magnus Damm <damm+renesas@...nsource.se>, Arnd Bergmann <arnd@...db.de>, Robin Murphy <robin.murphy@....com>, Will Deacon <will.deacon@....com>, linux-kernel@...r.kernel.org Subject: [PATCH] iommu/dma: fix function declaration Newly added code in the ipmmu-vmsa driver showed a small mistake in a header file that can't be included by itself without CONFIG_IOMMU_DMA enabled: In file included from drivers/iommu/ipmmu-vmsa.c:13:0: include/linux/dma-iommu.h:105:94: error: 'struct device' declared inside parameter list will not be visible outside of this definition or declaration [-Werror] This adds a forward declaration for 'struct device', similar to how we treat the other struct types in this case. Fixes: 3ae47292024f ("iommu/ipmmu-vmsa: Add new IOMMU_DOMAIN_DMA ops") Fixes: 273df9635385 ("iommu/dma: Make PCI window reservation generic") Signed-off-by: Arnd Bergmann <arnd@...db.de> --- include/linux/dma-iommu.h | 1 + 1 file changed, 1 insertion(+) diff --git a/include/linux/dma-iommu.h b/include/linux/dma-iommu.h index 4eac2670bfa1..92f20832fd28 100644 --- a/include/linux/dma-iommu.h +++ b/include/linux/dma-iommu.h @@ -78,6 +78,7 @@ void iommu_dma_get_resv_regions(struct device *dev, struct list_head *list); struct iommu_domain; struct msi_msg; +struct device; static inline int iommu_dma_init(void) { -- 2.9.0
