The problem was found when EDID data sets for displays other than the provided samples were generated. The patch has no effect on the provided samples that still match the data used in drivers/gpu/drm/drm_edid_load.c. The provided samples use small values for XOFFSET, XPULSE, YOFFSET and YPULSE, where the error doesn't occur. This fix corrects the use of that values in case of high values, because the most significant bits were treated incorrectly. So in edid.S msbs4 should use bit 8 and 9 of XOFFSET and XPULS. For YOFFSET and YPULSE msbs4 should use bit 4 and 5. lsbs2 was introduced for a better overview, without functional change. Removing also the useless value 63 of all files, because it is added in the *.S description files and then it is subtracted in edid.S.

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.
