From e3c75964666a27cec46d2cccf2d9806336becd48 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 23 Jan 2009 11:57:22 +0100 Subject: [PATCH] ALSA: hda - Create "Input Source" control dynamically for STAC/IDT Instead of fixed kcontrol_new element, build "Input Source" controls dynamically. If the number of input-source items is 0 or 1, we don't need to create such a control.
