From ca8d95c709378d0792c9dbacdab176a75e521ffb Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Thu, 22 Nov 2018 00:55:40 +0000 Subject: [PATCH] ASoC: simple-scu-card: tidyup "prefix" parsing simple-scu-card.c is supporting "prefix" which is used to avoid DAI naming conflict when CPU/Codec matching. But, sound card might have multi sub-devices, and each codec might need each prefix. Now, ASoC is supporting snd_soc_of_parse_node_prefix(), let's support it on audio-graph-scu-card, too. It is keeping existing DT style. It can't support each codec's prefix if sound card had multi sub-devices without this patch.
