Subject: [PATCH 0/3] platform/surface: aggregator: Add support for Surface Laptop Studio

This series adds Surface Aggregator Module (SAM) support for the new
Surface Laptop Studio (SLS).

This is mostly straight-forward addition of devices to the Surface
Aggregator registry, but the Surface HID driver needs a couple of small
changes. Specifically, we need to allow it to probe against SAM devices
with target ID 1 and also need to use the corresponding registry for
those.

I hope it's okay that I've CCed stable to get these included in v5.14+
stable kernels. The changes are fairly small and enable keyboard and
touchpad on the SLS. Most other things (except touch) should already
work well on the latest stable kernels, so back-porting this series
would make the SLS a usable device on those.
