The new functions are only used when CONFIG_PM is enabled, leading to a harmless warning:
sound/soc/codecs/rt5514-spi.c:474:12: error: 'rt5514_resume' defined but not used [-Werror=unused-function] sound/soc/codecs/rt5514-spi.c:464:12: error: 'rt5514_suspend' defined but not used [-Werror=unused-function]
This marks them as __maybe_unused to make the build silent again.
