linux-lts was recently updated from 5.15 to 6.1, which is the newest LTS kernel.
There was no patch to remove the hack. The patches that was present in 5.15 to enable the functionality has not applied for a while and has never been included in any of our linux 6.X kernels.
Although I have tried applying Megi’s versions, they seem to present other issues. The one I currently face is that if I enable the DP altmode patches, the keyboard and touchpad does not work on the Pinebook Pro. So they are currently not enabled.
The patches are hacks. They only work for some. And they only work in certain conditions, it seems. I deemed them unreliable and opted to no longer include them in kernel 5.18 and above.
