From daa480bde6b3a9b728965e52efffc329ccee3f77 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 7 Aug 2019 10:31:03 +0900 Subject: [PATCH] ASoC: soc-core: tidyup for snd_soc_dapm_add_routes() snd_soc_dapm_add_routes() registers routes by using for(... i < num; ...). If routes was NULL, num should be zero. Thus, we don't need to check about route pointer. This patch also cares missing return value.
