ALSA: hda - Fix duplicated DAC assignments for Realtek
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. Cc: <stable@kernel.org> (for 3.0) Signed-off-by: Takashi Iwai <tiwai@suse.de>
