The Asus GL502VSK has the same 0B05:1837 keyboard as we've seen in several Republic of Gamers laptops. However, in this model, the keybard backlight control exposed by hid-asus has no effect on the keyboard backlight. Instead, the keyboard backlight is correctly driven by asus-wmi. With two keyboard backlight devices available (and only the acer-wmi one working), GNOME is picking the wrong one to drive in the UI. Avoid this problem by not creating the backlight interface when we detect a WMI-driven keyboard backlight. We have also tested Asus GL702VMK which does have the hid-asus backlight present, and it still works fine with this patch (WMI method call returns UNSUPPORTED_METHOD). A direct "depends on ASUS_WMI" is intentionally avoided so that HID_ASUS users who have ASUS_WMI=n will not quietly lose their HID_ASUS driver on a kernel upgrade.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
