iommu/amd: Add missing function prototypes to fix -Wmissing-prototypes (9bdc2ef6) · Commits · 戴 / test

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) Signed-off-by:
