Done. ghost_realtek already has the exact address, so only the DMI match
for 83QM was needed. Tested - the RT722 no longer appears under
/sys/bus/soundwire/devices/. Will send as patch 1/2 in v2.

It is in my tree (7.2.0-rc7), but best_effort is only ever set from the
topology name:

  topology.c: bool no_fallback = strstr(file, "dummy");

With a real sof_tplg_filename it is false, so sof_sdw_get_tplg_files()
returns 0 at SSP2-BT instead of skipping it, and the card fails to probe.
The comment above that line describes 'dummy' as meaning no monolithic
fallback exists, which is the case here - so I think it is the intended
mechanism, though this would be the first machine entry to use it. Happy
to do it differently if you prefer.

Thanks,
