The HDA codec driver issues snd_hda_codec_reset() at the error path of

Finally we have a proper infrastructure to generate the modaliases
automatically, let's move to hda_device_id from the legacy
hda_codec_preset that contains basically the same information.

The patch function hook is stored in driver_data field, which is long,
and we need an explicit cast.  Other than that, the conversion is
mostly straightforward.  Each entry is even simplified using a macro,
and the lengthy (and error-prone) manual modaliases got removed.

As a result, we achieved a quite good diet:

2f0eaad910 ALSA: hda - Fix bogus codec address check for mixer name assignment
The recent commit [7fbe824a0f: ALSA: hda - Update mixer name for the
lower codec address] tried to improve the mixer chip name assignment
in the order of codec address.  However, this fix was utterly bogus;
it checks the field set in each codec, thus this value is reset at
each codec creation, of course.  For really handling this priority,
the assignment has to be remembered in the common place, namely in
hda_bus, instead of hda_codec.

7fbe824a0f ALSA: hda - Update mixer name for the lower codec address
In most cases, we prefer the onboard codec as the primary device, thus
it's better to set it as the mixer name.  Currently, however, the
mixer name is updated per the device instantiation order, and user
gets often HDMI/DP or other seen as a mixer chip name.  Also, if a
codec name is renamed by the driver, the old chip name might be left
still as the mixer name.

This patch addresses these issues by remembering the chip address that
was referred as the mixer name.  When a codec with the same or lower
address gives its name, renew the mixer name accordingly, as it's
either the update of the codec name or we get likely the more
appropriate chip as the reference.

7f57d803ee ALSA: hda - Disable power_save_node for Thinkpads
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.

83510441bc ALSA: hda/tegra - async probe for avoiding module loading deadlock
The Tegra HD-audio controller driver causes deadlocks when loaded as a
module since the driver invokes request_module() at binding with the
codec driver.  This patch works around it by deferring the probe in a
work like Intel HD-audio controller driver does.  Although hovering
the codec probe stuff into udev would be a better solution, it may
cause other regressions, so let's try this band-aid fix until the more
proper solution gets landed.

In the commit [fa4f18b4f4: 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.

c7cd0ef66a ALSA: hda - Fix path power activation
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.

the NULL check on pcm->pcm, while leaving a potentially superfluous
check on pcm itself untouched.

a3b3a9db5d ALSA: hdsp: silence a sprinft() overflow warning
card->shortname is a 32 char string so the sprintf() can theoretically
overflow.  snd_rawmidi_new() can accept strings up to 64 bytes long.

I have made the temporay buf[] array 40 bytes long and changed the
sprintf() to snprintf().

fa4f18b4f4 ALSA: hda - Refresh widgets sysfs at probing Haswell+ HDMI codecs
Intel Haswell (and later) codec refreshes the widgets tree to expose
the whole widget nodes at probing.  However, this refresh was missing
for sysfs tree.

This patch adds the missing piece, as we have now a proper API.

9e46aedab3 ALSA: hdsp: silence and underflow warning
I believe this probably cannot happen, as the code suggests.  There
would have to be an kcontrol->index.id which was zero, otherwise this
would be prevented in snd_ctl_find_id().  But snd_BUG_ON() is just a
WARN() or a no-op so static checkers complain that we keep on going with
a negative offset.  Let's just handle the error as well as printing
a warning.

f6b28e4ded ALSA: hda - Shutdown CX20722 on reboot/free to avoid spurious noises
On shutdown/reboot of CX20722, first shut down all EAPDs, then
shut down the afg node to D3.

Failure to do so can lead to spurious noises from the internal speaker
directly after reboot (and before the codec is reinitialized again, i e
in BIOS setup or GRUB menus).

The power states in a proc file are printed in a racy manner on a
single static string buffer.  Fix it by calling snd_iprintf() directly
for each state instead of processing on a temporary buffer.

d2c6b63df5 ALSA: hda - Make some helper functions local
A few helper functions to convert the pin information to strings have
been exported with assumption that they were used by other drivers.
But they are referred only in the proc interface in the end.

Let's make them local so that we can get rid of a few exports.
