There is some complicated logic in lemote-2f/pm.c. During wakeup, it creates a delayed_work to execute a callback to the function yeeloong_report_lid_status(). It's only purpose is to report the current status of the laptop lid switch, and this callback function wan not implemented in the mainline kernel.
This level of overenginnering hardly makes sense. All we need is to report the laptop lid switch unconditionally upon wakeup in the future PM code, which is being worked on.
