Subject: [PATCH] [UBUNTU:sound/pci/hda/] Fix erroneous re-initialisation of pins

UpstreamStatus: Added in upstream alsa-kernel hg changeset:
                0dc37f0a3a6a [http://hg-mirror.alsa-project.org/alsa-kernel?cmd=changeset;node=0dc37f0a3a6a921441a9e95094f1a5a9f168e9f0;style=raw]

In hda_codec.c::snd_hda_multi_out_analog_prepare(), check if hp_nid is
identical to the front pin to avoid re-initialising it.
