[PATCH 000/113] ALSA: add snd_pcm_is_playback/capture() macro

[Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>]

Hi ALSA-ML
Cc Staging-ML, USB-ML

Many drivers are using below code to know the Sound direction.

	if (direction == SNDRV_PCM_STREAM_PLAYBACK)

This patch-set add snd_pcm_is_playback/capture() macro to handle it.

Thank you for your help !!

Best regards
