From 25b8d31488a3fb3611651991969526b2ea475764 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Thu, 10 Jan 2013 23:43:56 +0800 Subject: [PATCH] ASoC: fsl: fix multiple definition of init_module With commit f2818d0 (ASoC: fsl: fix miscompilation of snd-soc-imx-pcm), we will see the following build error when building modules with CONFIG_SND_IMX_SOC=m in imx_v6_v7_defconfig.
