ad2109d7d2 ASoC: Updates for v3.10
A bunch of changes here, the most interesting one subsystem wise being
 Morimoto-san's work to create snd_soc_component which doesn't do much
 for now but will be pretty important going forwards:
 
  - Add a new component object type which will form the basis of moving
    to a more generic handling of SoC and off-SoC components, contributed
    by Kuninori Morimoto.
  - A fairly large set of cleanups for the dmaengine integration from
    Lars-Peter Clausen, starting to move towards being able to have a
    generic driver based on the library.
  - Performance optimisations to DAPM from Ryo Tsutsui.
  - Support for mixer control sharing in DAPM from Stephen Warren.
  - Multiplatform ARM cleanups from Arnd Bergmann.
  - New CODEC drivers for AK5385 and TAS5086 from Daniel Mack.

73bdd59782 ALSA: hda - Implement headset jack functionality for some Dell hw
On some machines, there is a headset jack that can support both
headphone, headsets (of both CTIA and OMTP type) and mic-in.

On other machines, the headset jack supports headphone, headsets

8fc24426f1 Revert "ALSA: hda - Allow power_save_controller option override DCAPS"
This reverts commit 6ab317419c.

The commit [6ab317419c: ALSA: hda - Allow power_save_controller option
override DCAPS] changed the behavior of power_save_controller so that
it can override the driver capability.  This assumed that this option
is rarely changed dynamically unlike power_save option.  Too naive.

It turned out that the user-space power-management tool tries to set
power_save_controller option to 1 together with power_save option
without knowing what's actually doing.  This enabled forcibly the
runtime PM of the controller,  which is known to be broken om many
chips thus disabled as default.

So, the only sane fix is to revert this commit again.  It was intended
to ease debugging/testing for runtime PM enablement, but obviously we
need another way for it.

4abdbd1c2c ALSA: hda - VIA prefers side surrounds over HP
The recent fix for the independent HP reduced the availability of the
side surround output, because there are only 4 DACs for 7.1 and a HP
outputs.  Adjust the badness tables for VIA so that 7.1 outputs are
activated for the cost of missing independent HP.

Once when we implement the dynamic DAC switching to multiple outputs,
this conflicts will be eased in future...

55a63d4da3 ALSA: hda - Fix DAC assignment for independent HP
The generic parser should evaluate the availability of the independent
HP when specified.  Otherwise a DAC without the direct connection to
the corresponding pin may be assigned for the HP, but the driver
doesn't check it at all.  The problem was actually seen on some
machines with VT1708s or equivalent codec, where DAC0 is assigned to
HP although it can be connected only via aamix.

This patch adds the badness evaluation for the independent HP to make
it working properly.

Headset mic jacks, i e TRRS style jacks with Headphone Left,
Headphone Right, Mic and GND signals, are becoming increasingly
common and are now being shipped by several manufacturers.

Unfortunately, the HDA specification does not give us any hint
of whether a Mic pin belongs to such a jack or not, but it would
still be helpful for the user to know (especially if there is one
TRS Mic jack and one TRRS headset jack).

This new fixup causes the first (non-dock, non-internal) mic to
be a headset mic jack. The algorithm can be later refined if needed.

eb49faa6a4 ALSA: hda - Fix abuse of snd_hda_lock_devices() for DSP loader
The current DSP loader code abuses snd_hda_lock_devices() for ensuring
the DSP loader not conflicting with the other normal operations.  But
this trick obviously doesn't work for the PM resume since the streams
are kept opened there where snd_hda_lock_devices() returns -EBUSY.
That means we need another lock mechanism instead of abuse.

This patch provides the new lock state to azx_dev.  Theoretically it's
possible that the DSP loader conflicts with the stream that has been
already assigned for another PCM.  If it's running, the DSP loader
should simply fail.  If not -- it's the case for PM resume --, we
should assign this stream temporarily to the DSP loader, and take it
back to the PCM after finishing DSP loading.  If the PCM is operated
during the DSP loading, it should get an error, too.

ba615b86d6 ALSA: hda - Don't apply EAPD power filter as default
So far, the driver doesn't power down the widget at going down to D3
when the widget node has an EAPD capability and EAPD is actually set
on all codecs unless codec->power_filter is set explicitly.
This caused a problem on some Conexant codecs, leading to click
noises, and we set it as NULL there.  But it is very unlikely that the
problem hits only these codecs.

Looking back at the development history, this workaround for EAPD was
introduced just for some laptops with STAC9200 codec, then we applied
it blindly for all.  Now, since it's revealed to have an ill effect,
we should disable this workaround per default and apply only for the
known requiring systems.

The EAPD workaround is implemented now as snd_hda_codec_eapd_power_filter(),
and this has to be set explicitly by the codec driver when needed.
As of now, only patch_stac9200() sets this one.

b5f82b1044 ALSA: hda - Fix snd_hda_get_num_raw_conns() to return a correct value
In the connection list expansion in hda_codec.c and hda_proc.c, the
value returned from snd_hda_get_num_raw_conns() is used as the array
size to store the connection list.  However, the function returns
simply a raw value of the AC_PAR_CONNLIST_LEN parameter, and the
widget list with ranges isn't considered there.  Thus it may return a
smaller size than the actual list, which results in -ENOSPC in
snd_hda_get_raw_conections().

This patch fixes the bug by parsing the connection list correctly also
for snd_hda_get_num_raw_conns().

eb7c06e8e9 ALSA: add/change some comments describing function return values
script/kernel-doc reports the following type of warnings (when run in verbose
mode):

Warning(sound/core/init.c:152): No description found for return value of
'snd_card_create'

To fix that:
- add missing descriptions of function return values
- use "Return:" sections to describe those return values

Along the way:
- complete some descriptions
- fix some typos
