From f8fdd4958b6c7af9abf630f06d43db4ddcd532f6 Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Mon, 15 Sep 2008 22:41:31 +0800 Subject: [PATCH] ALSA: HDA VIA: Fix crash on codecs without Headphone Don't enumerate via_hp_mixer while hp_mux is null (headphone does not exist), to fix the crash of via_independent_hp_info (via_hp_mixer's .info), which will reference hp_mux.
