a7a0a64dab ALSA: hda - Always call standard unsolicited event for Realtek codecs
With the model parsers out of the way, we have no custom unsol
events to worry about, we can therefore simplify the code.

In addition, this fixes a bug on the ASUS TC710, which has only
a headphone jack and a mic jack, but no internal mic or speakers.
Therefore the unsol_event pointer was not set, and as a result,
the jack kcontrols were not correctly updated.

0920c9b4c4 ALSA: hda - Remove beep_mode=2
The beep_mode=2 option was introduced to make the beep mixer
controlling the beep input allocation/deallocation dynamically, so
that a user can switch between HD-audio codec digital beep and the
system beep only via mixer API.  This was necessary because the
keyboard driver took only the first input beep instance at that time.

However, the recent keyboard driver already processes the multiple
input instances, thus there is no point to keep this mode.

Let's remove it.

The recent fix for power-map controls (commit b0791dda81) caused
regressions on some other HP laptops.  They have fixed pins but these
pins are exposed as jack-detectable.  Thus the driver tries to control
the power-map dynamically per jack detection where it never gets on.

This patch adds the check of connection and it assumes the no jack
detection is available for fixed pins no matter what pin capability
says.

125821ae53 ALSA: hda - Add the inverted digital mic workaround to Realtek codecs
Some laptops are equipped with ForteMedia digital mics that give the
differential input.  With such devices, summing stereo streams into a
mono (like PulseAudio does) results in almost silence.

This patch provides a workaround for this bug by adding a new mixer
switch to turn on/off the right channel of digital mic, just like a
similar fix for Conexant codecs.

When the new switch "Inverted Internal Mic Capture Switch" is off and
the current input source is the digital mic, the right channel of the
recording stream is muted.  When another input source is selected, the
right channel is restored.

b4a91cf05c ALSA: hda - Handle open while transitioning to D3.
This addresses an issue encountered when a pcm is opened while
transitioning to low power state (codec->power_on == 1 &&
codec->power_transition == -1).  Add snd_pcm_power_up_d3wait to
hda_codec.  This function is used to power up from azx_open as opposed
to snd_hda_power_up used from codec_exec_verb. When powering up from
azx_open, wait for pending power downs to complete, avoiding the power
up continuing in parallel with the power down on the work queue.

The specific issue seen was with the CS4210 codec, it powers off the ADC
and DAC nid in its suspend handler.  If it is re-opened before the
~100ms power down process completes, the ADC and DAC nid are initialized
while powered down and audio is lost until another suspend/resume cycle.

5daf53a6eb [media] snd_tea575x: Make the module using snd_tea575x the fops owner
Before this patch the owner field of the /dev/radio# device fops was set to
the snd-tea575x-tuner module itself. Meaning that the module which was using
it could be rmmod-ed while the device is open, and then BAD things happen.

I know, as I found out the hard way :)

Note that there is no need to also somehow increase the refcount of the
snd-tea575x-tuner module itself, since any drivers using it will have
symbolic references to it.

3de5ff8877 ALSA: hda - add support for HD-Audio CODECes of VIA HDMI GFX Cards
This is patch supporting the CODECes of HD-Audio function of VIA GFX
cards which support HDMI.
For CODECes 0x9f80/0x9f81, which belong to VX900, since the hardware
is not fully compliant to HD-Audio 1.3, simple_i*() is adopted
temporarily.

8393ec4a13 ALSA: hda - HDMI Audio init all connectors when VGA-switcheroo is off
When VGA_SWITCHEROO support is enabled hda_intel initialises the HDMI
audio device on the current VGA device.  When it's not enabled it only
initialises the HDMI device on the default VGA adaptor, this means
secondary cards get no audio support which is very unhelpful for
multi-seat!

With this patch, when SUPPORT_VGA_SWITCHEROO is disabled hda_intel
initialises all HDMI audio devices, not just the default VGA.
