During route setup, playback stream routes are setup by going through sink path, capture stream routes are set up by going through source path. This is not sufficient to handle loopback cases between pipelines configured with different directions, e.g. a sidetone or an amplifier feedback connected to a speaker protection module. So, add the logic to handle such routes between widgets that aren't in the list of DAPM widgets associated with the same PCM.

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.
