3f50ac6a0e ALSA: hda - Fix stream and channel-ids codec-bus wide
The new sticky PCM parameter introduced the delayed clean-ups of
stream- and channel-id tags.  In the current implementation, this check
(adding dirty flag) and actual clean-ups are done only for the codec
chip.  However, with HD-audio architecture, multiple codecs can be
on a single bus, and the controller assign stream- and channel-ids in
the bus-wide.

In this patch, the stream-id and channel-id are checked over all codecs
connected to the corresponding bus.  Together with it, the mutex is
moved to struct hda_bus, as this becomes also bus-wide.

4f34760787 ALSA: hda - Fix conflict of sticky PCM parameter in HDMI codecs
Intel and Nvidia HDMI codec drivers have own implementations of
sticky PCM parameters.  Now HD-audio core part already has it,
thus both setups conflict.  The fix is simply remove the part in
patch_intelhdmi.c and patch_nvhdmi.c and simply call
snd_hda_codec_setup_stream() as usual.

56385a12d9 ALSA: emu10k1 - delay the PCM interrupts (add pcm_irq_delay parameter)
With some hardware combinations, the PCM interrupts are acknowledged
before the period boundary from the emu10k1 chip. The midlevel PCM code
gets confused and the playback stream is interrupted.

It seems that the interrupt processing shift by 2 samples is enough
to fix this issue. This default value does not harm other,
non-affected hardware.

f0cea79724 ALSA: hda - Fix dynamic ADC change working again
The commit eb541337b7
    ALSA: hda - Make converter setups sticky
changes the semantics of snd_hda_codec_cleanup_stream() not to clean up
the stream at that moment but delay the action.  This broke the codes
expecting that the clean-up is done immediately, such as dynamic ADC
changes in some codec drivers.

This patch fixes the issue by introducing a lower helper,
__snd_hda_codec_cleanup_stream(), to allow the immediate clean up.
The original snd_hda_codec_cleanup_stream() is kept as is now.

bbbe33900d ALSA: hda - Restrict PCM parameters per ELD information over HDMI
When a device is plugged over HDMI, it passes some information in ELD
including the supported PCM parameters like formats, rates, channels.
This patch adds the check to PCM open callback of HDMI streams so that
only valid parameters the device supports are used.

When no device is plugged, the parameters the codec supports are used;
it's mostly all parameters the hardware can work.  This is for apps
that are started before device plugging and do probing (e.g. a sound
daemon), so that at least, probing would work even before the device
plugging.

53bacfbbb2 ALSA: hda - Fix missing stream for second ADC on Realtek ALC260 HDA codec
I discovered tonight that ALSA no longer sets up a stream for the second ADC
provided by the Realtek ALC260 HDA codec.  At some point alc_build_pcms()
started using stream_analog_alt_capture when constructing the second ADC
stream, but patch_alc260() was never updated accordingly.  I have no idea
when this regression occurred.  The trivial patch to patch_alc260() given
below fixes the problem as far as I can tell.  The patch is against 2.6.35.

eb541337b7 ALSA: hda - Make converter setups sticky
So far, we reset the converter setups like the stream-tag, the
channel-id and format-id in prepare callbacks, and clear them in
cleanup callbacks.  This often causes a silence of the digital
receiver for a couple of seconds.

This patch tries to delay the converter setup changes as much as
possible.  The converter setups are cached and aren't reset as long
as the same values are used.  At suspend/resume, they are cleared
to be recovered properly, too.

954a29c881 ALSA: hda - Prefer VREF50 if BIOS sets for Realtek codecs
If BIOS sets up the input pin as VREF 50, use the value as is instead of
overriding forcibly to VREF 80.  This fixes the quality of inputs on
some devices like Packard-Bell M5210.

5d4abf93ea ALSA: hda - Handle missing NID 0x1b on ALC259 codec
Since ALC259/269 use the same parser of ALC268, the pin 0x1b was ignored
as an invalid widget.  Just add this NID to handle properly.
This will add the missing mixer controls for some devices.

757899acee ALSA: hda - Share digital I/O parser in patch_realtek.c
Make a helper function to parse the digital I/Os of all Realtek codecs
to simplify the code and to ensure the setups.
Also, initialize digital I/O pins properly in init callbacks.  Some BIOS
seem to leave pins uninitialized.
