[ Upstream commit f7a7f80ccc8df017507e2b1e1dd652361374d25b ] When setting the guid via configfs it is possible to test if its value is one of the kernel supported ones by calling uvc_format_by_guid on it. If the result is NULL, we know the guid is unsupported and can be ignored.

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.
