For a long time now the acpi_video driver reports evdev brightness up/down key events for the brightness hotkeys on most (non ancient) laptops. asus-wmi also reports evdev brightness up/down key events for these keys leading to each press being reported twice and e.g. GNOME increasing the brightness by 2 steps instead of 1 step. Use the acpi_video_handles_brightness_key_presses() helper to detect if acpi_video is reporting brightness key-presses and if it is then don't report the same events also from the asus-wmi driver. Note there is a chance that this may lead to regressions where the brightness hotkeys stop working because they are not actually reported by the acpi_video driver. Unfortunately the only way to find out if this is a problem is to try. To at least avoid regressions on old hw using the eeepc-wmi driver, implement this as a key filter in asus-nb-wmi so that the eeepc-wmi driver is not affected.

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.
