Subject: ALSA: hda - Fix duplicated DAC assignments for Realtek
From: Takashi Iwai <[email protected]>
commit c48a8fb0d31d6147d8d76b8e2ad7f51a2fbb5c4d upstream.
Copying hp_pins and speaker_pins from line_out_pins may confuse the
parser, and it can lead to duplicated initializations for the same pin
with a wrong DAC assignment. The problem appears in 3.0 kernel code.
