From 5fa7553dcd83c576c589fd3e617dc599e4fe15dc Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Tue, 30 Mar 2021 14:26:38 +0900 Subject: [PATCH] ASoC: soc-core: use device_unregister() if rtd allocation failed Because soc_free_pcm_runtime(rtd) checks rtd pointer and freeing rtd->xxx, it doesn't work correctly in case of rtd allocation failed. We need to use device_unregister(dev) in such case. This patch fixup it.
