From 00966dcdf0e324e10ab79d505732c339f72417d9 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 25 Jul 2018 23:00:53 +0200 Subject: ALSA: usb-audio: Declare the common variable in header file Declare snd_usb_feature_unit_ctl properly in mixer.h. Otherwise it's error-prone. This fixes the sparse warning: sound/usb/mixer.c:1464:25: warning: symbol 'snd_usb_feature_unit_ctl' was not declared. Should it be static?
