From 338d7159c488268dd4ccc6a69ab4af8f829f75d0 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Thu, 22 Nov 2018 00:57:09 +0000 Subject: [PATCH] ASoC: audio-graph-scu-card: tidyup asoc_simple_card_parse_daifmt() timing Current audio-graph-scu-card driver is parsing codec position for DPCM and consider DAI format. But, current operation is doing totally pointless, because 1) asoc_simple_card_parse_daifmt() will be called not only for 1st codec on current implementation, and it will be used as fixed format 2) it should be called for each CPU/Codec pair. Let's tidyup asoc_simple_card_parse_daifmt() timing.
