"Add back" suggests that this line existed before this change. It
didn't, as far as I can see. Probing has

acm_set_control(acm, acm->ctrlout);

*shutdown* has

acm_set_control(acm, acm->ctrlout = 0);

Did you mean that I should try adding back the acm_set_control() during
shutdown, or the one during probe?
