As this issue still affects one of our users in Debian, is there
anything which can be done to unblock the situation? Does that mean
that the proposed patch is not good for the microphone device?

My understanding is that it fixes at least Staffan's case which
regressed from 1a8953f4f774 ("HID: Add IGNORE quirk for
SMARTLINKTECHNOLOGY").

#89729

Thank you Salvatore, for moving this forward.

I can add that the issue has been reported by several users on a GPD DUO 
channel on Discord -- all are on newer kernels but have different Linux 
distributions.

I can also confirm that the patch does solve my problem. Looking forward 
to some resolution of this, as it stops me from upgrading to Testing. :)

Best regards,

Staffan
