From 888afa15418f001896bc11f498f9348e029611bd Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 18 Mar 2008 09:57:50 +0100 Subject: [ALSA] hda-codec - keep the format verb at closing PCM streams Keep the format verb at closing PCM streams. Introduced snd_hda_codec_cleanup_stream() for the parcicular purpose.
