Eeep ?
clocksource_resume is called from timekeeping_resume()
timestatic int timekeeping_resume(struct sys_device *dev)
{
unsigned long flags;
unsigned long now = read_persistent_clock();
clocksource_resume();
....
}
keeping_resume() called via the sysdev resume
static struct sysdev_class timekeeping_sysclass = {
.resume = timekeeping_resume,
.suspend = timekeeping_suspend,
set_kset_name("timekeeping"),
};
