Add __maybe_unused prefix for addressing the following warnings:   sound/soc/codecs/cs43130.c:2615:12: warning: ‘cs43130_runtime_resume’ defined but not used [-Wunused-function]   sound/soc/codecs/cs43130.c:2596:12: warning: ‘cs43130_runtime_suspend’ defined but not used [-Wunused-function]

Isn't it better to guard it with CONFIG_PM?

thanks, Daniel.
