As Oliver pointed out, you need to explain why this is needed. More importantly, the patch is completely wrong. The "power/wakeup" parameter is not meant for controlling runtime resume; it is supposed to be used only for system resume. Yes, userspace has no choice about wakeup during runtime suspend. It is controlled entirely by the driver. If userspace wants to change the settings, it has to inform the driver somehow. But why would userspace want to change the setting?
