The table id (second) argument to MODULE_DEVICE_TABLE is often referenced otherwise. This is not the case for CPU features. This leads to a warning when building the kernel with Clang: arch/arm/crypto/crc32-ce-glue.c:239:33: warning: variable 'crc32_cpu_feature' is not needed and will not be emitted [-Wunneeded-internal-declaration] static const struct cpu_feature crc32_cpu_feature[] = { ^ Avoid warnings by using __maybe_unused, similar to commit 1f318a8b ("modules: mark __inittest/__exittest as __maybe_unused").
