Bug 215561 - snd-usb-audio:reset_resume error -22 after suspend (fwd from bugzilla)

Tue Feb 8 13:14:43 CET 2022

Hi, this is your Linux kernel regression tracker speaking.

Top-posting for once, to make this easy accessible to everyone.

Below issue is one of those those reports that seem to get stranded in
bugzilla.kernel.org

Greg, Jaroslav, Takashi, could one of you please take a look? The
reporter submitted it as USB bug, but maybe that wasn't a wise choice.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I'm getting a lot of
reports on my table. I can only look briefly into most of them and lack
knowledge about most of the areas they concern. I thus unfortunately
will sometimes get things wrong or miss something important. I hope
that's not the case here; if you think it is, don't hesitate to tell me
in a public reply, it's in everyone's interest to set the public record
straight.
