From: Kuninori Morimoto Date: Mon, 10 Jul 2023 01:20:17 +0000 (+0900) Subject: ASoC: soc-core.c: add snd_soc_copy_dai_args() X-Git-Tag: v6.6.7~1940^2^2~204^2~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bbde4a30c6b18dd034dcce41612907dc64817175;p=platform%2Fkernel%2Flinux-starfive.git 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.
