@tlaurion @mkukri Yes, it appears to be roughly what I and Mate were telling you to do. This is what you will have to do for now, until Mate finishes upstreaming the T480 patch.
We don't need to do anything ourselves at present; we will do our own things on our own time.
I annoyed mkukri on IRC when I asked him to prioritise this, going along from what you demanded - yes, demanded. You made such a fuss over it repeatedly, rather than doing it yourself. Demanding we do things on your schedule.
