mainlining shenanigans

Child min_brightness is obsolete from VBT 234+, instead the new min_brightness field in the main structure should be used. This new field is 16 bits wide, so backlight_precision_bits is needed to check if value needs to be scaled down but it is only available in VBT 236+ so working around it by using the also new backlight_level in the main struct. v2: - missed that backlight_data->level is also obsolete v3: - s/backlight/brightness to better match specification - using u16 to specify brightness level instead of a u32 : 16 BSpec: 20149 Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201008211932.24989-1-jose.souza@intel.com |

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.
