From: Maximilian Luz <luzmaximilian@gmail.com>
commit 4f042e40199ce8bac6bc2b853e81744ee4ea759c upstream.
Add support for the Surface Laptop Studio.
In contrast to previous Surface Laptop models, this one has its HID devices attached to target ID 1 (instead of 2). It also has a couple more of them, including a new notifier for when the pen is stashed / taken out of its place, a "Sys Control" device, and two other unidentified HID devices with unknown usages.
Battery and performance profile interfaces remain the same.
