      ALSA: hda - Enforces runtime_resume after S3 and S4 for each codec · 19184190
      由 Hui Wang 提交于 
      commit b5a236c175b0d984552a5f7c9d35141024c2b261 upstream.

Recently we found the audio jack detection stop working after suspend
on many machines with Realtek codec. Sometimes the audio selection
dialogue didn't show up after users plugged headhphone/headset into
the headset jack, sometimes after uses plugged headphone/headset, then
click the sound icon on the upper-right corner of gnome-desktop, it
also showed the speaker rather than the headphone.

The root cause is that before suspend, the codec already call the
runtime_suspend since this codec is not used by any apps, then in
resume, it will not call runtime_resume for this codec. But for some
realtek codec (so far, alc236, alc255 and alc891) with the specific
BIOS, if it doesn't run runtime_resume after suspend, all codec
functions including jack detection stop working anymore.

This problem existed for a long time, but it was not exposed, that is
because when problem happens, if users play sound or open
sound-setting to check audio device, this will trigger calling to
runtime_resume (via snd_hda_power_up), then the codec starts working
again before users notice this problem.

Since we don't know how many codec and BIOS combinations have this
problem, to fix it, let the driver call runtime_resume for all codecs
in pm_resume, maybe for some codecs, this is not needed, but it is
harmless. After a codec is runtime resumed, if it is not used by any
apps, it will be runtime suspended soon and furthermore we don't run
suspend frequently, this change will not add much power consumption.

      ALSA: hda - Record the current power state before suspend/resume calls · 156ba57f
      由 Takashi Iwai 提交于 
      commit 98081ca62cbac31fb0f7efaf90b2e7384ce22257 upstream.

Currently we deal with single codec and suspend codec callbacks for
all S3, S4 and runtime PM handling.  But it turned out that we want
distinguish the call patterns sometimes, e.g. for applying some init
sequence only at probing and restoring from hibernate.

This patch slightly modifies the common PM callbacks for HD-audio
codec and stores the currently processed PM event in power_state of
the codec's device.power field, which is currently unused.  The codec
callback can take a look at this event value and judges which purpose
it's being called.

      ALSA: hda/ca0132 - make pci_iounmap() call conditional · c8e91d75
      由 Arnd Bergmann 提交于 
      commit 1e73359a24fad529b0794515b46cbfff99e5fbe6 upstream.

When building without CONFIG_PCI, we can (depending on the architecture)
get a link failure:

ERROR: "pci_iounmap" [sound/pci/hda/snd-hda-codec-ca0132.ko] undefined!

Adding a compile-time check for PCI gets it to work correctly on
32-bit ARM.

Another machine which does not like the power saving (noise):

Also, reorder the Lenovo C50 entry to keep the table sorted.

      ALSA: hda/realtek - Fixed hp_pin no value · 1ac48daf
      由 Kailang Yang 提交于 
      commit 693abe11aa6b27aed6eb8222162f8fb986325cef upstream.

Fix hp_pin always no value.

[More notes on the changes:

 The hp_pin value that is referred in alc294_hp_init() is always zero
 at the moment the function gets called, hence this is actually
 useless as in the current code.

 And, this kind of init sequence should be called from the codec init
 callback, instead of the parser function.  So, the first fix in this
 patch to move the call call into its own init_hook.

 OTOH, this function is needed to be called only once after the boot,
 and it'd take too long for invoking at each resume (where the init
 callback gets called).  So we add a new flag and invoke this only
 once as an additional fix.

 The one case is still not covered, though: S4 resume.  But this
 change itself won't lead to any regression in that regard, so we
 leave S4 issue as is for now and fix it later.  -- tiwai ]
