commit d21a91629f4b8e794fc4c0e0c17c85cedf1d806c upstream. Despite our heuristics to not wrongly export a non working ACPI backlight interface on desktop machines, we still end up exporting one on desktops using a motherboard from the MSI MS-7721 series. I've looked at improving the heuristics, but in this case a quirk seems to be the only way to solve this. While at it also add a comment to separate the video_detect_force_none entries in the video_detect_dmi_table from other type of entries, as we already do for the other entry types.

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.
