From d13bd412dce23eed8bc35a2499d7d88cb39a1581 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 30 Jul 2008 15:01:45 +0200 Subject: [PATCH] ALSA: hda - Manage kcontrol lists Manage all kcontrol elements created in the hda-intel driver. This makes it possible to remove and reconfigure the controls of each codec.
