Without a ll-driver callback hid_hw_may_wakeup() will return: device_may_wakeup(hdev->dev.parent), but for the hid devices instantiated by logitech-dj for devices behind the receiver the logitech-dj hid(pp)-device is the parent. Add a logi_dj_ll_may_wakeup() callback which calls hid_hw_may_wakeup() on the logitech-dj hid(pp) parent-hid-device.
