[alsa-devel] [PATCH 4/4] ASoC: rt715: Add __maybe_unused to PM callbacks

[Takashi Iwai]

Fix the compile warnings by adding __maybe_unused to PM callbacks:
  sound/soc/codecs/rt715-sdw.c:566:12: warning: ‘rt715_dev_resume’ defined but not used [-Wunused-function]
  sound/soc/codecs/rt715-sdw.c:552:12: warning: ‘rt715_dev_suspend’ defined but not used [-Wunused-function]

Fixes: d1ede0641b05 ("ASoC: rt715: add RT715 codec driver")
