Laurent Pinchart d0e3ab637d drm: rcar-du: Fix CRTC timings when CMM is used
[ Upstream commit f0ce591dc9a97067c6e783a2eaccd22c5476144d ]

When the CMM is enabled, an offset of 25 pixels must be subtracted from
the HDS (horizontal display start) and HDE (horizontal display end)
registers. Fix the timings calculation, and take this into account in
the mode validation.

This fixes a visible horizontal offset in the image with VGA monitors.
HDMI monitors seem to be generally more tolerant to incorrect timings,
but may be affected too.

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.
