From 193e813814775b1b1574515fc6f11e61b29a54f7 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Wed, 16 Apr 2008 09:13:36 +0200 Subject: [ALSA] oxygen: generalize handling of DAC volume limits Add fields for the DAC volume limits to the module structure so that model drivers do not need to install their own control info handlers.
