The suspend/resume functions in the s5p-cec driver are only referenced when CONFIG_PM is enabled, so we get a warning about unused functions otherwise: drivers/staging/media/s5p-cec/s5p_cec.c:260:12: error: 's5p_cec_resume' defined but not used [-Werror=unused-function] static int s5p_cec_resume(struct device *dev) ^~~~~~~~~~~~~~ drivers/staging/media/s5p-cec/s5p_cec.c:253:12: error: 's5p_cec_suspend' defined but not used [-Werror=unused-function] static int s5p_cec_suspend(struct device *dev) This marks them as __maybe_unused to avoid the warning without having to introduce an extra #ifdef.
