[PATCH v2 4/9] dma-iommu: Fix compilation when !CONFIG_IOMMU_DMA

From: Marc Zyngier
Date: Tue May 08 2018 - 08:16:46 EST

Inclusion of include/dma-iommu.h when CONFIG_IOMMU_DMA is not selected
results in the following splat:

In file included from drivers/irqchip/irq-gic-v3-mbi.c:20:0:
./include/linux/dma-iommu.h:95:69: error: unknown type name âdma_addr_tâ
static inline int iommu_get_msi_cookie(struct iommu_domain *domain, dma_addr_t base)
./include/linux/dma-iommu.h:108:74: warning: âstruct list_headâ declared inside parameter list will not be visible outside of this definition or declaration
static inline void iommu_dma_get_resv_regions(struct device *dev, struct list_head *list)
scripts/Makefile.build:312: recipe for target 'drivers/irqchip/irq-gic-v3-mbi.o' failed

Fix it by including linux/types.h.
