The drm_of_lvds_get_data_mapping() returns either negative value on
error or MEDIA_BUS_FMT_* otherwise. The check for 'ret' would also
catch the positive case of MEDIA_BUS_FMT_* and lead to probe failure
every time 'data-mapping' DT property is specified.
Fixes: 7c4dd0a266 ("drm: of: Add drm_of_lvds_get_data_mapping")

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.
