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. Signed-off-by: Takashi Iwai <tiwai@suse.de>
