Compiling amd_iommu_debugfs.c seems to depend only on CONFIG_IOMMU_DEBUG. Can we prevent the code within amd_iommu_debugfs.c from getting compiled when either CONFIG_AMD_IOMMU or CONFIG_IOMMU_DEBUG is disabled? > obj-$(CONFIG_AMD_IOMMU_V2) += amd_iommu_v2.o > obj-$(CONFIG_ARM_SMMU) += arm-smmu.o > obj-$(CONFIG_ARM_SMMU_V3) += arm-smmu-v3.o
