From 934b96594ed66b07dbc7e576d28814466df3a494 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sun, 12 Apr 2020 10:13:31 +0200 Subject: ALSA: usb-audio: Check mapping at creating connector controls, too Add the mapping check to build_connector_control() so that the device specific quirk can provide the node to skip for the badly behaving connector controls. As an example, ALC1220-VB-based codec implements the skip entry for the broken SPDIF connector detection.
