Subject: ALSA: hda - Record all detected ADCs in hda_gen_spec
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0ffd534eb164fbc87e91fc54a217247ea0cfbabc;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

ALSA: hda - Record all detected ADCs in hda_gen_spec

Since the generic parser reduces the ADC list, copy the list of the
all detected ADCs and keep it.

This list can be later referred by the codec driver for finer power
controls.
