Subject: [PATCH] platform/surface: aggregator_registry: Add support for
Surface Laptop Studio
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.
