-Subject: [PATCH] bump the sensitivity of AMD SFH
-
-Bumps the sensitivity of AMD sfh gyro and accelerometers by removing the division
-operation and rebasing the units in the hid descriptor.
-This helps with the gyro deadzone of the Legion Go. Should not affect existing
-devices.
-
-Since most of the magic happens in firmware thej SFH 1.0 HID report descriptor is left untouched.

-Subject: [PATCH] platform/surface: aggregator_registry: Add support for
- Surface Laptop 6
-
-Add SAM client device nodes for the Surface Laptop Studio 6 (SL6). The
-SL6 is similar to the SL5, with the typical battery/AC, platform
-profile, and HID nodes. It also has support for the newly supported fan
-interface.
