    ALSA: hda - Create snd_hda_get_conn_index() helper function

    Create snd_hda_get_conn_index() helper function for obtaining the
    connection index of the widget.  Replaced the similar codes used in
    several codec-drivers with this common helper.

    ALSA: hda - More volume-init fixes for ALC267 codec

    More similar fixes like previous commits: handle the exceptional case
    like ALC267 where no volume amp is found in ADC widget but in the
    capsrc widget instead.

    Also minor checks for avoiding possible erros: no connection-select
    when the pin has a single selection, and add beep verbs only when the
    0x1d is used for beep.

To be even more sure, I re-synced your branch again and built a new
kernel. The patch_realtek.c file being built is here:
http://belegdol.fedorapeople.org/patch_realtek.c
Fresh alsa-info.sh is here:
http://www.alsa-project.org/db/?f=5051b2cb788b1db4273e06e98a78783dd0ec679f

belegdol4 is the suffix I added:
$ uname -r
3.0-0.rc5.git0.1.belegdol4.fc15.x86_64

Node 0x02 [Audio Output] wcaps 0x41d: Stereo Amp-Out
  Control: name="Headphone Playback Volume", index=0, device=0

Perhaps I need to specify a correct model to enable this code?
