From 9b98c7c2a0599084c7ed629b5f88f474d2578307 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 7 Aug 2019 10:31:08 +0900 Subject: [PATCH] ASoC: soc-core: tidyup for snd_soc_add_card_controls() snd_soc_add_card_controls() registers controls by using for(... i < num; ...). If controls was NULL, num should be zero. Thus, we don't need to check about controls pointer. This patch also cares missing return value.
