RE: [PATCH v17 00/12] input: cyapa: instruction of cyapa patches

Thanks, Jeremiah.

It seems the power manage code has been updated in kernel-next,
the same code didn't genereate any error before.
I updated with latest kernel-next, the compiling error also happened.
To fix this code, need to add stubs for cyapa_runtime_suspend() and
cyapa_runtime_resume() when CONFIG_PM_RUNTIME is not defined.

 #ifdef CONFIG_PM_RUNTIME
 static int cyapa_runtime_suspend(struct device *dev)
 {
 struct cyapa *cyapa = dev_get_drvdata(dev);
 int error;

 error = cyapa->ops->set_power_mode(cyapa,
 cyapa->runtime_suspend_power_mode,
 cyapa->runtime_suspend_sleep_time);
 if (error)
 dev_warn(dev, "runtime suspend failed: %d\n", error);

 return 0;
 }

 static int cyapa_runtime_resume(struct device *dev)
 {
 struct cyapa *cyapa = dev_get_drvdata(dev);
 int error;

 error = cyapa->ops->set_power_mode(cyapa, PWR_MODE_FULL_ACTIVE, 0);
 if (error)
 dev_warn(dev, "runtime resume failed: %d\n", error);

 return 0;
 }
+#else
+static inline int cyapa_runtime_suspend(struct device *dev) { return 0; }
+static inline int cyapa_runtime_resume(struct device *dev) { return 0; }
 #endif /* CONFIG_PM_RUNTIME */

 static const struct dev_pm_ops cyapa_pm_ops = {
 SET_SYSTEM_SLEEP_PM_OPS(cyapa_suspend, cyapa_resume)
 SET_RUNTIME_PM_OPS(cyapa_runtime_suspend, cyapa_runtime_resume, NULL)
 };

Thanks,
dudley
