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 1f318a8bafcf
("modules: mark __inittest/__exittest as __maybe_unused").
Fixes: 2a9faf8b7e43 ("crypto: arm/crc32 - enable module autoloading based on CPU feature bits")
