Building with CONFIG_OF=n triggers: warning: 'rk3308_codec_of_match' defined but not used [-Wunused-const-variable=] warning: unused variable 'rk3308_codec_of_match' [-Wunused-const-variable] Even though OF is needed for probing, fix by declaring as __maybe_unused to still allow building on non-OF configurations for build testing.
