From 3653480c68120dc16ebfeb80e529200dbbd98f92 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Tue, 31 Jan 2023 02:02:04 +0000 Subject: [PATCH] ASoC: soc-dai.h: cleanup Playback/Capture data for snd_soc_dai Current snd_soc_dai has data for Playback/Capture, but it is very random. Someone is array (A), someone is playback/capture (B), and someone is tx/rx (C); struct snd_soc_dai { ... (A) unsigned int stream_active[SNDRV_PCM_STREAM_LAST + 1]; (B) struct snd_soc_dapm_widget *playback_widget; (B) struct snd_soc_dapm_widget *capture_widget; (B) void *playback_dma_data; (B) void *capture_dma_data; ... (C) unsigned int tx_mask; (C) unsigned int rx_mask; }; Because of it, the code was very complicated. This patch creates new data structure to merge these into one, and tidyup the code.
