- * state - Control current power state of device
- *
- * show() returns the current power state of the device. '0' indicates
- * the device is on. Other values (2) indicate the device is in some low
- * power state.
- *
- * store() sets the current power state, which is an integer valued
- * 0, 2, or 3. Devices with bus.suspend_late(), or bus.resume_early()
- * methods fail this operation; those methods couldn't be called.
- * Otherwise,
- *
- * - If the recorded dev->power.power_state.event matches the
- * target value, nothing is done.
- * - If the recorded event code is nonzero, the device is reactivated
- * by calling bus.resume() and/or class.resume().
- * - If the target value is nonzero, the device is suspended by
- * calling class.suspend() and/or bus.suspend() with event code
- * PM_EVENT_SUSPEND.
- *
- * This mechanism is DEPRECATED and should only be used for testing.
