commit 32cf4023e689ad5b3a81a749d8cc99d7f184cb99 upstream.
When an IRQ for some reason gets lost, we wait up to a second using
udelay, which is CPU intensive. This patch improves the situation by
waiting about 30 ms in the CPU intensive mode, then stepping down to
using msleep(2) instead. In essence, we trade some granularity in
exchange for less CPU consumption when the waiting time is a bit longer.As a result, PulseAudio should no longer be killed by the kernel
for taking up to much RT-prio CPU time. At least not for *this* reason.Signed-off-by: David Henningsson

commit c914f55f7cdfafe9d7d5b248751902c7ab57691e upstream.
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.ALSA sound/pci/echoaudio/echoaudio.c:2061 Echoaudio driver starting...

commit 3868137ea41866773e75d9ac4b9988dcc361ff1d upstream.
Some codecs don't supply the mute amp-capabilities although the lowest
volume gives the mute. It'd be handy if the parser provides the mute
mixers in such a case.This patch adds an extension amp-cap bit (which is used only in the
driver) to represent the min volume = mute state. Also modified the
amp cache code to support the fake mute feature when this bit is set
but the real mute bit is unset.In addition, conexant cx5051 parser uses this new feature to implement
the missing mute controls.Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=42825

[Note that since the patch isn't applicable (and unnecessary) to
3.3-rc, there is no corresponding upstream fix.]The cx5051 parser calls snd_hda_input_jack_add() in the init callback
to create and initialize the jack detection instances. Since the init
callback is called at each time when the device gets woken up after
suspend or power-saving mode, the duplicated instances are accumulated
at each call. This ends up with the kernel warnings with the too
large array size.The fix is simply to move the calls of snd_hda_input_jack_add() into
the parser section instead of the init callback.The fix is needed only up to 3.2 kernel, since the HD-audio jack layer
was redesigned in the 3.3 kernel.Reported-by: Russell King

The refactoring of Realtek codec driver in 3.2 kernel caused a

commit b4ead019afc201f71c39cd0dfcaafed4a97b3dd2 upstream.
The recent change of the power-widget handling for IDT codecs caused
the silent output from the docking-station line-out jack. This was
partially fixed by the commit f2cbba7602383cd9cdd21f0a5d0b8bd1aad47b33
"ALSA: hda - Fix the lost power-setup of seconary pins after PM resume".
But the line-out on the docking-station is still silent when booted
with the jack plugged even by this fix.The remainig bug is that the power-widget is set off in stac92xx_init()
because the pins in cfg->line_out_pins[] aren't checked there properly
but only hp_pins[] are checked in is_nid_hp_pin().This patch fixes the problem by checking both HP and line-out pins
and leaving the power-map correctly.Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=42637

commit fc084e0b930d546872ab23667052499f7daf0fed upstream.
There are some AC97 codec and board combinations that have been observed
to take a very long time to respond after the cold reset has completed.
In one case, more than 350 ms was required. To allow users to have sound
on those platforms, we'll wait up to 500ms for the codec to become
ready.As a board may have multiple codecs, with some faster than others to
reset, we add a module parameter to inform the driver which codecs
should be present.Reported-by: KotCzarny

commit aeb4b88ec0a948efce8e3a23a8f964d3560a7308 upstream.
When a virtual mater control is created, the driver looks for slave
elements from the assigned card instance. But this may include the
elements of other codecs when multiple codecs are on the same HD-audio
bus. This works at the first time, but it'll give Oops when it's once
freed and re-created via reconfig sysfs.This patch changes the element-look-up strategy to limit only to the
mixer elements of the same codec.Reported-by: David Henningsson

commit 6b45214277bec2193ad3ccb8d7aa6100b5a0f1a9 upstream.
It seems that Conexant CX20549 chip handle only a single input-amp even
though the audio-input widget has multiple sources. This has been never
clear, and I implemented in the current way based on the debug information
I got at the early time -- the device reacts individual input-amp values
for different sources. This is true for another Conexant codec, but it's
not applied to CX20549 actually.This patch changes the auto-parser code to handle a single input-amp
per audio-in widget for CX20549. After applying this, you'll see only a
single "Capture" volume control instead of separate "Mic" or "Line"
captures when the device is set up to use a single ADC.We haven't tested 20551 and 20561 codecs yet. If these show the similar
behavior like 20549, they need to set spec->single_adc_amp=1, too.Signed-off-by: Takashi Iwai
