Previously, when the camera toggle switch was hit, the hp-wmi driver would report an invalid event code. By adding a case for that in the event handling switch statement we can eliminate that error code and enable a framework for potential further kernel handling of that key. This change was tested on my HP Envy x360 15-ey0023dx laptop, but it would likely work for any HP laptop with a camera toggle button. Now we emit an SW_CAMERA_LENS_COVER event, on a device that gets created on the first such event so as to not report incorrectly the state of the camera shutter before we can know its state.

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.
