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.
