From 596becd3f82a7b7e091b0f5c380bc9a0e6758126 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 7 Aug 2019 10:31:36 +0900 Subject: ASoC: soc-core: dai_link check under soc_dpcm_debugfs_add() soc_dpcm_debugfs_add(rtd) is checking rtd->dai_link pointer, but, rtd->dai_link->dynamic have been already checked before calling it. static int soc_probe_link_dais(...) { dai_link = rtd->dai_link; ... => if (dai_link->dynamic) => soc_dpcm_debugfs_add(rtd); ... } void soc_dpcm_debugfs_add(rtd) { => if (!rtd->dai_link) return; ... } These pointer checks are strange/pointless. This patch checks dai_link->dynamic under soc_dpcm_debugfs_add().
