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.
