Few exported functions from AMD IOMMU driver are missing prototypes. They have declaration in arch/x86/events/amd/iommu.h but this file cannot be included in the driver. Add prototypes to fix W=1 warnings like:
drivers/iommu/amd/init.c:3066:19: warning: no previous prototype for 'get_amd_iommu' [-Wmissing-prototypes] 3066 | struct amd_iommu *get_amd_iommu(unsigned int idx)
