From 363129ea90e0835b8552b797714cd200f674e287 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sat, 16 Oct 2010 13:24:52 -0400 Subject: ALSA: fix unused warnings with snd_power_get_state If we compile the ASoC code with PM disabled, we hit stuff like: sound/soc/soc-dapm.c: In function 'snd_soc_dapm_suspend_check': sound/soc/soc-dapm.c:440: warning: unused variable 'codec' So tweak the stub macro to avoid these issues.
