From 983cebd602af8c2bf9d5830f15fb4e18fb38f994 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 10 Aug 2016 02:20:19 +0000 Subject: [PATCH] ASoC: simple-card-utils: add asoc_simple_card_canonicalize_cpu() simple-card needs remove dai_link->cpu_dai_name if it CPU was single DAI. This patch makes this method simple style standard.
