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").
