From 1c9096f32ad23f5867e752f238fd25e4fec55ecd Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 17 Oct 2022 23:36:49 +0000 Subject: ASoC: soc-dapm.c: ignore parameter NULL at snd_soc_dapm_free_widget() Currently snd_soc_dapm_free_widget() is assuming input parameter is non NULL. Thus, caller need to care about it. This patch care it at snd_soc_dapm_free_widget().
