The association numbers of surround/CLFE speaker pins aren't correctly
mapped by the auto-parser.  This patch fixes the CLFE speaker pin to the
right assoc value (from 3 to 1).

When 5.1 or more headphone or speaker pins are provided, the parser still
takes as is without fixing the order of channel mapping, which leads in
the unexpected strange channel order by surround outputs.

This patch fixes the issue by applying the same fix-up not only to
line_out_pins[] but also hp_pins[] and speaker_pins[].

When a device has multiple speakers and still has the auto-mute support,
the driver copies line_outs[] to speaker_outs[].  And then it tries to
assign DACs for both.  This ended up with the assignment only to the
primary DAC to all speakers.

This patch fixes the situation by checking the duplicated LO/SPK case
appropriately.

This is patch for Conexant codec of Intel HDA driver, adding new quirk
for Lenovo Thinkpad T520 and W520. Conexant autodetection works fine for
T520 (similar subsystem ID is used also in W520 model) and detects more
mixer features compared to generic (fallback) Lenovo quirk with
hardcoded options in Conexant codec.

Patch was activelly tested with Linux 3.0.4, 3.0.6 and 3.0.7 without any
problems.

The audio_feature_info[] array should contain all entries for UAC2_FU_*,
but currently a few last entries are missing.  Even though, the driver
tries to probe these entries in parse_audio_feature_unit() and may

the loop size properly using ARRAY_SIZE() instead of a hard-coded

The commit ef18bede introduced a
mechanism to assign the previously used slot for the next reopen of a
PCM stream.  But the PCM device number isn't always unique (it may
have multiple substreams), and also the code doesn't check the stream
direction, thus both playback and capture streams share the same
device number.

For avoiding this conflict, make a unique key for each substream and
store/check this value at reopening.

When the speaker outputs are more than the headphone outputs, it implies
that the system has surround speakers while the headphones are only for
monitoring the front.  In such a case, it's better to put speakers as
the primary outputs so that the driver can build up and keep the
surround setup.  Otherwise the system will pick up the headphone as
primary, and offers less channels than the speakers do support.

This is mostly a static checker fix more than anything else.  We're
copying from a 64 char buffer into a 44 char buffer.

The 64 character buffer is str[] in snd_mixer_oss_build_test_all().
The call tree is:
	snd_mixer_oss_build_test_all()
	-> snd_mixer_oss_build_test()
	   -> snd_mixer_oss_build_test().

We never actually do fill str[] buffer all the way to 64 characters.
The longest string is:
	sprintf(str, "%s Playback Switch", ptr->name);
ptr->name is a 32 character buffer so 32 plus 16 characters for
" Playback Switch" still puts us over the 44 limit from "id.name".

Most likely ptr->name never gets filled to the limit, but we can't
really change the size of that buffer so lets just use strlcpy() here
and be safe.

* Channel Mode
  This is an enum control to change the surround-channel setup,
  appears only when the surround channels are available.
  It gives the number of channels to be used, "2ch", "4ch" abd "6ch".
  According to the configuration, this also controls the
  jack-retasking of multi-I/O jacks.

* Independent HP
  When this enum control is enabled, the headphone output is routed
  from an individual stream (the third PCM such as hw:0,2) instead of
  the primary stream.

Added a new option "snoop" for the traffic control of the HD-audio
controller chip.  When set to 0, the non-snooping mode is used with
the traffic control bit is set in each stream control register.
This may allow better operations in the low power mode, but the actual
implementation is depending pretty much on the chipset.

As already implemented, more or less each chipset has own snoop-control
register bit.  Now this setup refers to the snoop option, too.

Also, a new VIA chipset may require the non-snooping mode when set so
in BIOS.  In such a case, the option value is overridden.

As default, it's still set to snoop=1 for keeping the same behavior as
before.  In near future, it'll be set to 0 as default after checking
it works in every system well.
