From 201e06ffa9ef9b5265e636617f4fa20cd1490343 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 16 Nov 2011 15:33:26 +0100 Subject: [PATCH] ALSA: hda - Give more unique names by snd_hda_get_pin_label() The function now gives more unique names for the output pins by adding some prefix and suffix for the location and the channels. Otherwise, it can pass the index number.
