From: Kuninori Morimoto Date: Tue, 4 Mar 2014 04:50:24 +0000 (-0800) Subject: ASoC: rsnd: call rsnd_scu_ssi_mode_init() from SSI X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=221bf523e31306c1095b28932e079950108e3887;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git ASoC: rsnd: call rsnd_scu_ssi_mode_init() from SSI Current R-Car sound driver is assuming that SCU mod is used even though it is not needed. Because scu.c is controlling SSIU too. (it is Gen1 compatibility) But, SCU mod will be really not used if new platform dai feature was added. Thus, rsnd_scu_ssi_mode_init() is called from SSI directory by this patch.
