Subject: ALSA: hda - Fix initialization of secondary capture source on VT1705
From: Takashi Iwai <[email protected]>
commit fc1156c0b0f7ad45ec03d919866349eeca2bf18c upstream.
VT1705 codec has two ADCs where the secondary ADC has no MUX but only
a fixed connection to the mic pin. This confused the driver and it
tries always overriding the input-source selection by assumption of
the existing MUX for the secondary ADC, resulted in resetting the
input-source at each time PM (including power-saving) occurs.
The fix is simply to check the existence of MUX for secondary ADCs in
the initialization code.
