Good question.

The initial code was in

6d2c66695bf3 ("soundwire: intel: transition to 3 steps initialization")

but then moved with

08c2a4bc9f2a ("ALSA: hda: move Intel SoundWire ACPI scan to dedicated
module")

I guess a Fixes tag for the latter is good enough, it's a 2021 commit
and that would probably cover most SoundWire platforms.
