From 4417932315d185b59c0089091de7fa509c59fd5a Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 28 Jul 2009 17:03:49 +0200 Subject: [PATCH] ALSA: hda - Don't create unneeded digital input source for IDT 92HD71x The current driver creates always the digital input source mixer elements for IDT 92HD71x codecs no matter whether digital mics are present. This patch adds the proper check to avoid the creation of these controls if unnecessary.
