there are three concepts represent backlight in int3406_thermal driver. 1. the raw brightness value from native graphics driver. 2. the percentage numbers from ACPI _BCL control method. 3. the consecutive numbers represent cooling states. int3406_thermal driver 1. uses value from DDDL/DDPC as the lower/upper limit, which is consistent with ACPI _BCL control methods. 2. reads current and maximum brightness from the native graphics driver. 3. expose them to thermal sysfs I/F This patch fixes the code that switches between the raw brightness value and the cooling state, which results in bogus value in thermal sysfs I/F.

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.
