From ef991b95aa1351a5782cfaccb9aefba76ca8b990 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 22 Feb 2007 12:52:53 +0100 Subject: [ALSA] Add snd_pcm_group_for_each_entry() for code cleanup Added a new macro snd_pcm_group_for_each_entry() just for code cleanup. Old macros, snd_pcm_group_for_each() and snd_pcm_group_substream_entry(), are removed.
