      ALSA: hda - Disable power_save_node for Thinkpads · 7f57d803
      由 Takashi Iwai 提交于 
      Lenovo Thinkpads with recent Realtek codecs seem suffering from click
noises at power transition since the introduction of widget power
saving in 4.1 kernel.  Although this might be solved by some delays in
appropriate points, as a quick workaround, just disable the
power_save_node feature for now.  The gain it gives is relatively
small, and this makes the situation back to pre 4.1 time.

This patch ended up with a bit more code changes than usual because
the existing fixup for Thinkpads is highly chained.  Instead of adding
yet another chain, combine a few of them into a single fixup entry, as
a gratis cleanup.

      vga_switcheroo: Set active attribute to false for audio clients · 21b45676
      由 Lukas Wunner 提交于 
      The active attribute in struct vga_switcheroo_client denotes whether
the outputs are currently switched to this client. The attribute is
only meaningful for vga clients. It is never used for audio clients.

The function vga_switcheroo_register_audio_client() misuses this
attribute to store whether the audio device is fully initialized.
Most likely there was a misunderstanding about the meaning of
"active" when this was added.

Comment from Takashi's review:

"Not really.  The full initialization of audio was meant that the audio
is active indeed.  Admittedly, though, the active flag for each audio
client doesn't play any role because the audio always follows the gfx
state changes, and the value passed there doesn't reflect the actual
state due to the later change.  So, I agree with the removal of the
flag itself -- or let the audio active flag following the
corresponding gfx flag.  The latter will make the proc output more
consistent while the former is certainly more reduction of code."

Set the active attribute to false for audio clients. Remove the
active parameter from vga_switcheroo_register_audio_client() and
its sole caller, hda_intel.c:register_vga_switcheroo().

vga_switcheroo_register_audio_client() was introduced by 3e9e63db
("vga_switcheroo: Add the support for audio clients"). Its use in
hda_intel.c was introduced by a82d51ed ("ALSA: hda - Support
VGA-switcheroo").

v1.1: The changes above imply that in find_active_client() the call
to client_is_vga() is now superfluous. Drop it.

      ALSA: hda - Refresh sysfs at snd_hda_codec_update_widgets() · 9dcc144b
      由 Takashi Iwai 提交于 
      In the commit [fa4f18b4: ALSA: hda - Refresh widgets sysfs at
probing Haswell+ HDMI codecs], snd_hdac_refresh_widget_sysfs() is
explicitly called in the codec driver.  But this results in refreshing
twice, as snd_hdac_refresh_widget_sysfs() itself calls
snd_hdac_refresh_widgets() function.

Instead, we can replace the call in snd_hda_codec_update_widgets()
with snd_hdac_refresh_widget_sysfs().  This also fixes the missing
sysfs update for ca0132, too.

      ALSA: hda - Fix path power activation · c7cd0ef6
      由 Takashi Iwai 提交于 
      The widget power-saving code tries to turn up/down the power of each
widget in the I/O paths that are modified at each jack plug/unplug.
The recent report revealed that the power activation leaves some
widgets unpowered after plugging.  This is because
snd_hda_activate_path() turns on path->active flag at the end of the
function while the path power management is done before that.  Then
it's regarded as if nothing is active, and the driver turns off the
power.

The fix is simply to set the flag at the beginning of the function,
before trying to power up.

      ALSA: hda - Check all inputs for is_active_nid_for_any() · 9d2b48f7
      由 Takashi Iwai 提交于 
      The is_active_nid_for_any() function in the generic parser is supposed
to check all connections from/to the given widget, but the current
code checks only the first input connection (index = 0).

This patch corrects the code to check all inputs by passing -1 to
index argument.

      ALSA: hda - Fix pin config and mapping on Alienware 15 · fe14f39e
      由 Takashi Iwai 提交于 
      Alienware 15 has CA0132 codec for its onboard sound, but the pin
config and mapping seem quite different from other Creative boards.
This patch corrects them, at least, for providing the right headphone
and mic jack notification, as well as removing the non-existing SPDIF
pins.

Even with this fix, not all stuff works perfectly yet, mainly because
of the badly written ca0132 driver code -- it has too many implicit
assumptions of pin configs and maps.  Nevertheless, this is a small
good step forward.
