Add a Surface System Aggregator Module (SSAM) client device hub for hot-removable devices managed via the KIP subsystem. The KIP subsystem (full name unknown, abbreviation has been obtained through reverse engineering) is a subsystem that manages hot-removable SSAM client devices. Specifically, it manages HID input devices contained in the detachable keyboard cover of the Surface Pro 8 and Surface Pro X. The KIP subsystem handles a single group of devices (e.g. all devices contained in the keyboard cover) and cannot handle devices individually. Thus we model it as a client device hub, which (hot-)removes all devices contained under it once removal of the hub (e.g. keyboard cover) has been detected and (re-)adds all devices once the physical hub device has been (re-)attached. To do this, use the previously generified SSAM subsystem hub framework.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
