From de12ffd5bd2ac41e3b76d8f62b4e2a26104a8882 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sun, 12 Apr 2020 10:13:29 +0200 Subject: [PATCH] ALSA: usb-audio: Don't override ignore_ctl_error value from the map commit 3507245b82b4362dc9721cbc328644905a3efa22 upstream. The mapping table may contain also ignore_ctl_error flag for devices that are known to behave wild. Since this flag always writes the card's own ignore_ctl_error flag, it overrides the value already set by the module option, so it doesn't follow user's expectation. Let's fix the code not to clear the flag that has been set by user.
