From 4b1c88984c8ac894c2c411570757bed7fa5f3226 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 18 May 2017 15:13:57 +0200 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.
