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.
