These functions can be assigned to the ->runtime_idle(), ->runtime_suspend(),

These functions are the defaults used by the PM core, if a subsystem doesn't

provide its own callbacks for ->runtime_idle(), ->runtime_suspend(),

If a subsystem wishes to use all of them at the same time, it can simply assign

the GENERIC_SUBSYS_PM_OPS macro, defined in include/linux/pm.h, to its

dev_pm_ops structure pointer.
