[ Upstream commit3986457110] Commit5cca30ebe0("drm/rcar-du: Add LVDS_LANES quirk") states that LVDS lanes 1 and 3 are inverted on R-Car H2 ES1 only, and that the problem has been fixed in newer revisions. However, the code didn't take into account the actual hardware revision, thus applying the quirk also on newer hardware revisions, causing green color reversals. Fix this by applying the quirk when running on R-Car H2 ES1.x only.

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.
