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,
