If an HDMI connector has no EDID and the mode is set via the
kernel command line, then drm_reset_display_info() is the only
thing that will have set up any of connector->display_info.
With commit 26ff1c38fc ("drm/connector: hdmi: Compute bpc
and format automatically"), it is now checked that
DRM_COLOR_FORMAT_RGB444 is supported. Whilst it doesn't fail
the request, it does log dev_warn for every commit, spamming
the log.
For HDMI connectors initialise the color_format field to say
it supports RGB444.

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.
