[PATCH 5.7 336/393] ALSA: usb-audio: fix overeager device match for MacroSilicon MS2109

From: Greg Kroah-Hartman
Date: Mon Aug 17 2020 - 14:44:03 EST


From: Hector Martin <marcan@xxxxxxxxx>

commit 14a720dc1f5332f3bdf30a23a3bc549e81be974c upstream.

Matching by device matches all interfaces, which breaks the video/HID
portions of the device depending on module load order.
