From 2f72853ca1ee1571377996471d05db51eb7c54c4 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 25 Sep 2008 16:32:41 +0200 Subject: [PATCH] ALSA: hda - Fix / clean-up slave digital out codes The recent slave_dig_out addition has some rooms to clean up. Also it doesn't call snd_hda_cleanup_stream() properly for slaves at closing. The patch fixes both issues.
