The config fragment doesn't follow the correct format to enable those config options which make the config options getting missed while merging with other configs.

➜ merge_config.sh -m .config tools/testing/selftests/iommu/config Using .config as base Merging tools/testing/selftests/iommu/config ➜ make olddefconfig .config:5295:warning: unexpected data: CONFIG_IOMMUFD .config:5296:warning: unexpected data: CONFIG_IOMMUFD_TEST

While at it, add CONFIG_FAULT_INJECTION as well which is needed for CONFIG_IOMMUFD_TEST. If CONFIG_FAULT_INJECTION isn't present in base config (such as x86 defconfig), CONFIG_IOMMUFD_TEST doesn't get enabled.
