From 51e19ca5f7555802687324d3bee3bc6b7df240d4 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 20 Jun 2018 17:06:58 +0200 Subject: [PATCH] ALSA: hda/conexant - Clean up beep code Like the previous commit for Realtek codec, the similar cleanup work can be applied to Conexant codec, too. A slight difference is that the call of cx_auto_parse_beep() is moved after snd_hda_gen_parse_auto_config(). It's not strictly needed, but it'd be good to make the creation of such beep mixers at the end, which matches with the former situation. Along with this conversion, cx_auto_build_controls() becomes just calling snd_hda_gen_build_controls(), so it's simply replaced with snd_hda_gen_build_controls.
