If devm_drm_of_get_bridge() can't find the connected bridge, it returns an ERR_PTR(-EPROBE_DEFER) to indicate that the probe should be deferred. But this path also prints an error message, which pollutes the kernel log since is printed on every probe deferral, i.e: $ dmesg | grep "failed to create panel bridge" | wc -l 38 Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Reviewed-by: Andrzej Hajda <andrzej.hajda@intel.com> Reviewed-by: Douglas Anderson <dianders@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20220722074755.660258-1-javierm@redhat.com
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.
