From bbde4a30c6b18dd034dcce41612907dc64817175 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 10 Jul 2023 10:20:17 +0900 Subject: ASoC: soc-core.c: add snd_soc_copy_dai_args() To use multi Component support, we need to check dai_args whether Card could get DAI from args (CPU/Codec needs set dai_args on DAI driver). If it could, we need to allocate dai_args for dlc. This patch adds snd_soc_copy_dai_args() for it. This is helper function for multi Component support.
