mainlining shenanigans
6f11586f48
The convention is that the SoundWire controller device is a child of the HDAudio controller. However there can be more than one child exposed in the DSDT table, and the current namespace walk returns the last (incorrect) device. Intel documentation states that bits 28..31 of the _ADR field represent the link type, with SoundWire assigned the value 4. Add a filter and terminate early when a valid _ADR is provided, otherwise keep iterating to find the next child.

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.
