In 2ch and 4ch modes, the front is also sent to the Line-out/side jack
for convenience instead of just muting the Line-out/side jack like other
models do.

- HDMI sink must tell HDMI source about its speaker placements
  (via ELD, speaker-allocation field)
- HDMI source must tell the HDMI sink about channel allocation

This patch attempts to set the CA(channel-allocation) byte in the audio infoframe
according to
- the number of channels in the current stream
- the speakers attached to the HDMI sink

A channel_allocations[] line must meet the following two criteria to be
considered as a valid candidate for CA:
1) its number of allocated channels = substream->runtime->channels
2) its speakers are a subset of the available ones on the sink side

If there are multiple candidates, the first one is selected.  This simple
policy shall cheat the sink into playing music, but may direct data to the
wrong speakers.

Some notes:

- Shall we show an empty file if the ELD content is not valid?
  Well it's not that simple. There could be partially populated ELD,
  and there may be malformed ELD provided by buggy drivers/monitors.
  So expose ELD as it is.

  others are/could be universal and independent ones.

- How do we name the proc file?
  If there are going to be two HDMI pins per codec, then the current naming
  scheme (eld#<codec no>) will fail. Luckily the user space dependencies should
  be minimal, so it would be trivial to do the rename if that happens.

- The ELD proc file content is designed to be easy for scripts and human reading.
  Its lines all have the pattern:
  <item_name>\t[\t]*<item_value>
  where <item_name> is a keyword in c language, while <item_value> could be any

ALSA: hda - Add lifebook model for Realtek ALC269

The widget layout of the Fujitsu Lifebook S6420 (which is ICH9M-based
and uses an ALC269) is similar but not identical to the Lifebook
S6410/E8410 (which are ICH8M-based and use an ALC262).

It is named lifebook as fujitsu is in use for Amilo machines. This builds
on the Quanta FL1 work and supports all analog inputs & outputs that I am
aware of.  Microphone autoswitch is implemented. The laptop mic port takes
precedence over the dock mic port if both happen to have a jack plugged in.
This made sense to me as a design decision (imagine a presentation
environment with the dock fully wired in and the presenter quickly wanting
to override the mic with a headset).

There is mention of a digital audio path on the codec graph, so perhaps
the headphone socket is dual-function analog/digital. I will follow up
with another patch if I can acquire equipment to test this.

ALSA: hda - Make codec-probing more robust

When an error occurs during the codec probing, typically accessing to an
non-existing codec slot, the controller chip gets often screwed up and
can no longer communicate with the codecs.

This patch adds a preparation phase just to probe codec addresses before
actually creating codec instances.  If any error occurs during this
probing phase, the driver resets the controller to recover.

This will (hopefully) fix the famous "single_cmd" errors.
