Subject: [RFC PATCH 0/2] soundwire: introduce controller ID

This patchset is an alternate proposal to the solution suggested in
[1], which breaks Intel machine drivers.

The only difference is to use a known controller ID instead of an IDA,
which wouldn't work with the hard-coded device name.

This patchset was tested on Intel and AMD platforms, testing on
Qualcomm platforms is required - hence the RFC status.
