When CONFIG_PM_SLEEP is disabled, we get a warning about unused functions: drivers/gpio/gpio-xgene.c:155:12: warning: 'xgene_gpio_resume' defined but not used [-Wunused-function] static int xgene_gpio_resume(struct device *dev) ^~~~~~~~~~~~~~~~~ drivers/gpio/gpio-xgene.c:142:12: warning: 'xgene_gpio_suspend' defined but not used [-Wunused-function] static int xgene_gpio_suspend(struct device *dev) The warnings are harmless and can be avoided by simplifying the code and marking the functions as __maybe_unused.
