ThinkPad 410,420,510,520 and X201 with cx50585 & co chips have the
docking-station ports, but BIOS doesn't initialize for these pins.
Thus, like the former X200, we need to set up the pins manually in the
driver.

The odd part is that the same PCI SSID is used for X200 and T400, thus
we need to prepare individual fixup tables for cx5051 and others.

Through the transition to the auto-parser, the support for
Quanta/Gericom KN1 got broken.  There are two problems behind it:

- This machine doesn't like the default COEF setup for ALC260 we take
  now as default

- BIOS doesn't set the pins correctly at all; especially the machine
  uses only the pin 0x0f for both headphone and speaker

This patch adds the fixup as a workaround for these issues.

In sound/pci/hda/patch_realtek.c::alc_auto_fill_dac_nids(), in the
'for (;;)' loop, if the 'badness' value returned from
fill_and_eval_dacs() is negative, then we'll return from the function
without freeing the memory we allocated for 'best_cfg', thus leaking.
Fix the leak by kfree()'ing the memory when badness is negative.

While I was there I also noticed some trailing whitespace in the
function that I removed (along with all other trailing whitespace in
the file) - it didn't seem worth-while to do that as two patches, so I
hope it's OK that I just did it all as one patch.

A user reported that setting model=imac24 used to allow sound to work on their
Mac Pro 5,1 machine.  Commit 5671087f "Move ALC885 macpro and imac24 models

handled with a quirk and the auto-parser.  This adds a quirk for the device

The recent Realtek driver tries to assign an extra input via the
headphone plug when only a single input source is found.  The code
worked on Samsung Q1, but it broke ASUS 1015 where the mic is a
digital-mic and only a specific ADC works.

This patch fixes the assignment of ADC in the shared mic/hp case.
Instead of assuming the single ADC at first, reduce the ADCs after
trying to assign both mic and HP pins.

The tea575x-tuner module has been updated to use the latest V4L2 framework
functionality. This also required changes in the drivers that rely on it.

The tea575x changes are:

- The drivers must provide a v4l2_device struct to the tea module.
- The radio_nr module parameter must be part of the actual radio driver,
  and not of the tea module.
- Changed the frequency range to the normal 76-108 MHz range instead of
  50-150.
- Add hardware frequency seek support.
- Fix broken rxsubchans/audmode handling.
- The application can now select between stereo and mono.
- Support polling for control events.
- Add V4L2 priority handling.

And radio-sf16fmr2.c now uses the isa bus kernel framework.

We've had ugly static handling of the mute-LED with a powersave hook
for ALC269 HP laptops just like done in patch_sigmatel.c.  This is now
rewritten with the new vmaster hook and a fixup code.

For that, the new fixup action, ALC_FIXUP_ACT_BUILD, is introduced.
It's called after build_controls is called.  The reason of this new
action is that vmaster hook must be added at this stage (not in init
or probe).
Signed-off-by: NTakashi Iwai <tiwai@suse.de>

The mute-LED is controlled in patch_sigmatel.c by (ab-)using the
powersave hook.  This can be now rewritten with the vmaster hook
instead, which is much simpler and can work even without
CONFIG_SND_HDA_POWER_SAVE kconfig.

A drawback is that the mute-LED corresponds _only_ to the Master mixer
switch instead of checking the whole DACs.  But usually this shouldn't
be a big problem as PA enables the mixer elements accordingly.

Also, this patch changes the code to create vmaster always even on
STAC9200 and STAC925x.  The former "Master" on these chips are renamed
as "PCM" now.

When the driver is changed to use vmaster or a new slave element is
added by the improvement of the parser code, user may face often the
silent output because of the muted slave mixer although Master volume
is properly set.  And they complain.  And I get upset.

Although such a mixer element should be initialized via "alsactl init",
it'd be more user-friendly if the known output slaves are unmuted and
set to 0dB so that user can control the volume only with Master as
default.  Since Master is still set muted as default even with this
change, no risk of the speaker blow up, too.

We've seen a problem with a pop-noise at suspend/resume on a HP
machine with ALC269, and it turned out to be an issue that the
controller going to D3 while the codec is unused.

When the device is once suspended and resumed and kept unused, the
driver doesn't initialize the codecs.  Instead, the codec chips are
set up dynamically at the first usage.  Now, suppose the device going
to suspend again before the codec is set up.  The controller is turned
off to D3 while the codec chips are untouched.  This caused a pop
noise because the codec chip might have been turned on implicitly by
the hardware.

As a workaround, the codec chip needs to be set to D3 when going to
suspend no matter whether it was used or not.  Also, for making it
happening, the controller has to be always set up in the resume path.
