    This statement/function help to send the device back to ROM (Unlock) if the PMBus become not responsive.
    Seems like someone commented this statement out, since in certain hardware the state of GPIO pins could not be guarantied/controlled.

    You should un-comment this statement if you want to unlock the device based on a combination of GPIO pin states.

    Regards,
