Some Asus laptops (verified on X550VXK/FX502VD/FX502VE) get no interrupts when pressing media keys thus the corresponding functions are not invoked. It's due to the _GPE defines in DSDT for EC returns differnt value compared to the GPE Number in ECDT. Confirmed with Asus that the vale in ECDT is the correct one. This commit uses DMI quirks to prevent calling _GPE when doing ec_parse_device() and keep the ECDT GPE number setting for the EC device. With previous commit, it is ensured that if there is an ECDT, it can always be kept as boot_ec, this patch thus can implement a quirk on top of the determined ECDT boot_ec.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
