From 07c93357b16b2652f2845548a598971bed36607c Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 27 Jul 2011 16:41:57 +0200 Subject: ALSA: hda - Fix duplicated DAC assignments for Realtek 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.
