Subject[PATCH 4.9 091/171] ALSA: hda - No loopback on ALC299 codec
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit fa16b69f1299004b60b625f181143500a246e5cb ]

ALC299 has no loopback mixer, but the driver still tries to add a beep
control over the mixer NID which leads to the error at accessing it.
This patch fixes it by properly declaring mixer_nid=0 for this codec.

Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=195775
Fixes: 28f1f9b26cee ("ALSA: hda/realtek - Add new codec ID ALC299")
