Apparently some BDW machines (eg. HP Pavilion 15-ab) shipped with a VBT inherited from some earlier HSW model. On HSW the HDMI level shift value could go up to 11, whereas on BDW the maximum value is 9. The DDI code does clamp the bogus value, but it does so with a WARN which we don't really want. To avoid that let's just sanitize the bogus VBT HDMI level shift value ahead of time for all BDW machines.

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.
