Is this the fix for
"aplay: set_params:1403: Unable to install hw params:"
which appeared in today's next (so after your last round of patches get merged)?
https://krzk.eu/#/builders/1/builds/3093/steps/24/logs/stdio

Also, since yesterday (so with previous rounds of patches) the audss
rebind freezes entire kernel:
https://krzk.eu/#/builders/1/builds/3093/steps/25/logs/stdio
https://krzk.eu/#/builders/1/builds/3093/steps/25/logs/serial0

It is not important test but it was always passing in my suite.

Best regards,
Krzysztof
