Currently the code assumes that the entire EDID extesion block can be taken up by the DispID blocks. That is not true. There is at least always the DispID checksum, and potentially fill bytes if the extension block uses the interior fill scheme to pad out to fill EDID block size. So let's not parse the checksum or the fill bytes as DispID blocks by having drm_find_displayid_extension() return the actual length of the DispID data to the caller.

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.
