acpi_backlight=native is the default for these, but as the comment explains the quirk was still necessary because even briefly registering the acpi_video0 backlight; and then unregistering it once the native driver showed up, was leading to issues. After the "ACPI: video: Make backlight class device registration a separate step" patch from earlier in this patch-series, we no longer briefly register the acpi_video0 backlight on systems where the native driver should be used. So this is no longer an issue an the quirks are no longer needed. Link: https://bugzilla.kernel.org/show_bug.cgi?id=215683 Tested-by: Werner Sembach <wse@tuxedocomputers.com> Acked-by: Rafael J.

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.
