commit df0380b9539b04c1ae8854a984098da06d5f1e67 upstream.
This is a fix equivalent with the upstream commit df0380b9539b ("ALSA: usb-audio: Add quirk for Audient iD14"), adapted to the earlier kernels up to 5.14.y. It adds the quirk entry with the old ignore_ctl_error flag to the usbmix_ctl_maps, instead.
The original commit description says: Audient iD14 (2708:0002) may get a control message error that interferes the operation e.g. with alsactl. Add the quirk to ignore such errors like other devices.
