	Add support for the legacy keyboard (KBD/TC=0x08) HID transport layer of the Surface System Aggregator Module (SSAM) to the Surface HID driver. On Surface Laptops 1 and 2, this interface is used to connect the integrated keyboard. Note that this subsystem interface essentially provides a limited HID transport layer. In contrast to the generic HID interface (TC=0x15) used on newer Surface models, this interface only allows (as far as we know) for a single device to be connected and is otherwise severely limited in terms of support for feature- and output-reports. Specifically, only caps-lock-LED output-reports and a single read-only feature-report are supported.

2021-03-30	HID: Add support for Surface Aggregator Module HID transport	Maximilian Luz	1	-0/+28
	Add a HID transport driver to support integrated HID devices on newer Microsoft Surface models (specifically 7th-generation, i.e. Surface Laptop 3, Surface Book 3, and later). On those models, the internal keyboard and touchpad (as well as some other HID devices with currently unknown function) are connected via the generic HID subsystem (TC=0x15) of the Surface System Aggregator Module (SSAM). This subsystem provides a generic HID transport layer, support for which is implemented by this driver.
