The tracing capabilities for the speaker protection fw enabled via
commit c55b3e46cb99 ("ASoC: wm_adsp: Add trace caps to speaker
protection FW") are not be available on all platforms, such as the
Valve's Steam Deck which is based on the Halo Core DSP.
As a consequence, whenever the firmware is loaded, a rather misleading
'Failed to parse legacy: -19' error message is written to the kernel
ring buffer:

Fixing this for a single firmware probably doesn't really make
the most sense, if we are treating buffers as optional these days
I guess really the best solution would be to make this either an
info and slightly rephrase the message or make it a dbg message.
Thanks,

Indeed, I have just submitted v2 for a more generic handling of the issue:
