Instead of direct calls to the link train functions, retrain the link via a commit modeset. The direct call means that the output port will be disabled/re-enabled while the rest of the pipeline (transcoder) is active, which doesn't seem to work on MST at least. It leads to underruns and black screen, presumedly because the transcoder is not disabled/re-enabled along the port. Leave switching to a commit modeset on SST for a later patchset, as that seems to work ok currently (though better to using a commit there too, due to the suppressed underruns). v2: Keep reverse line length order for local variables.

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 reStructuredText 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.
