Alexander Kobel 0a053f01fe platform/x86: thinkpad_acpi: Handle keyboard cover attach/detach events
Those events occur when a keyboard cover is attached to a ThinkPad
X1 Tablet series device.  Typically, they are used to switch from normal
to tablet mode in userspace; e.g., to offer touch keyboard choices when
focus goes to a text box and no keyboard is attached, or to enable
autorotation of the display according to the builtin orientation sensor.

intel-vtbn already recognizes those events.  To avoid sending duplicate
events to userspace, they are simply ignored.  Thus, this patch only
avoids warnings about unknown and unhandled HKEYs 0x4012 and 0x4013.

For more information about the background and potential improvements for
different types of attachment options, such as the Pico cartridge dock
module, see

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.
