The DisplayID CTA data block version does not necessarily match the CTA revision. Simplify by postponing drm_edid_to_eld() slightly, and reusing the CTA revision extracted by drm_parse_cea_ext(). By not bailing out early in drm_edid_to_eld() we may end up filling meaningless data to the ELD. However, the main decision for audio is not the ELD, but rather drm_detect_monitor_audio() called by drivers. (Arguably a future cleanup could do that in drm_add_edid_modes() and cache the result in the connector.)

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.
