Some power-saving states have been left unchanged in
snd_hda_codec_reset(), and this is a potential danger because the

This is a fix for the problem in commit 785f857d, the pop noise
issue on some machines with ALC269.  The problem was the uninitialized
state after the resume due to the delayed resume of the codec chips.
In that commit, we tried to fix by forcibly putting the codec to D3 at
suspend.  But, this still also leaves the uninitialized state after
resume, and it _might_ be still problematic with some BIOS.  Since the
commit turned out to regress another issues, we reverted it in the
end.

Now, in this fix, try to fix by turning on the codec immediately at
the resume path.  We need to take care of the power-saving in this
case.  When the device is woken up at the power-saved state, it should
go power-saving again after the resume.

Just a clean up by calling the same helper function.
Signed-off-by: NTakashi Iwai <tiwai@suse.de>

This reverts commit 785f857d.

The commit causes a problem with the wrong D3 state after suspend
because the call of hda_set_power_state() involves with the power-up
sequence, which changes the power_count, and this confuses the resume
sequence that checks the power_count as well.

Originally, this go-to-D3 sequence should be a simple task without the
power-up sequence.  But, it'd need some proper sanity checks in the
case of power-saved state, so it's not too easy to write now in the
3.4-rc cycle.

In short, the safest option now is to revert this affecting commit.

Of course, we need to clean up and robustify the power-saving code
better for 3.5 kernel.

This assertion seems to imply that chip->dsp_code_to_load is a pointer.
It's actually an integer handle on the actual firmware, and 0 has no
special meaning.

The assertion prevents initialisation of a Darla20 card, but would also
affect other models. It seems it was introduced in commit dd7b254d.

ASoC: updates for 3.4

Slightly larger than normal - the DAPM fix is a "this should always have
worked" type of thing which is very clear and should have no impact on
systems that don't need it.  The WM8994 fix is driver specific but
pretty important for that driver.

This ensures a clean startup of the channels, without this change some
use cases could result in issues in a small proportion of cases.

Signed-off-by: NTakashi Iwai <tiwai@suse.de>

For setting the pin-control values more safely to match with the
actual pin capability bits, a copule of new helper functions,
snd_hda_set_pin_ctl() and snd_hda_set_pin_ctl_cache(), are
introduced.  These are simple replacement of the codec verb write with
AC_VERB_SET_PIN_WIDGET but do more sanity checks and filter out
superfluous pin-control bits if they don't fit with the corresponding
pin capabilities.

Some codecs are screwed up or ignore the command when such a wrong bit
is set.  These helpers will avoid such secret errors.

Merge fixes for Thinkpad docking-station regressions for 3.3 kernels
back to 3.4.  These were committed in that branch to make the stable
merging easier.

Conflicts:
	sound/pci/hda/patch_conexant.c

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

- 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.
