Hans de Goede f6f4a0862b drm/i915/vlv_dsi: Add DMI quirk for backlight control issues on Lenovo Yoga Tab 3 (v2)
On the Lenovo Yoga Tab 3 Pro YT3-X90F there are 2 issues with the backlight
on/off MIPI sequences:

1. The backlight on sequence has an I2C MIPI sequence element which uses
   bus 0, but there is a bogus I2cSerialBus resource under the GPU in
   the DSDT which causes i2c_acpi_find_adapter() to pick the wrong bus.

2. There is no backlight off sequence, causing the backlight to stay on.

Add a DMI quirk fixing both issues.

v2:
- Add Closes tag to gitlab issue with drm.debug=0xe, VBT info

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.
