Input: twl4030-pwrbutton - report a wakeup_event on button press

As the power button causes a wake from suspend, we need to register the event with the pm sustem to avoid racing with suspend. As the input event is reported in the interrupt handler, as simple pm_wakeup_event() is sufficient. Signed-off-by: NeilBrown <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>
