Some models (or maybe depending on BIOS version) of Sony VAIO with
ALC260 give no proper pin configurations as default, resulting in the
non-working speaker, etc. Just provide the whole pin configurations

ALSA: hda - Fix unbalanced runtime PM notification at resume
When a codec is resumed, it keeps the power on while the resuming
phase via hda_keep_power_on(), then turns down via
snd_hda_power_down(). At that point, snd_hda_power_down() notifies
the power down to the controller, and this may confuse the refcount if
the codec was already powered up before the resume.
In the end result, the controller goes to runtime suspend even before
the codec is kicked off to the power save, and the communication
stalls happens.
The fix is to add the power-up notification together with
hda_keep_power_on(), and clears the flag appropriately.
You're looking at a casual headset patch,
for a specific hardware it will match,
and suddenly, the headset jack will work,
so please apply this simple quirk!

ALSA: jack: Unregister input device at disconnection
The recent change in sysfs triggered a kernel WARNING at unloading a
sound driver like

sysfs group ffffffff81ab7b20 not found for kobject 'event14'

device is done in dev_free callback, which is called after
snd_card_disconnect(). Since device_unregister(card->card_dev) is
called in snd_card_disconnect(), the whole sysfs entries belonging to
card->card_dev have been already removed recursively. Thus this
results in a warning as input_unregister_device() yet tries to
unregister the already removed sysfs entry.
For fixing this mess, we need to unregister the jack input device at
dev_disconnect callback so that it's called before unregistering the
card->card_dev.

ASoC: fsl: imx-pcm-fiq: omit fiq counter to avoid harm in unbalanced situations
Unbalanced calls to snd_imx_pcm_trigger() may result in endless
FIQ activity and thus provoke eternal sound. While on the first glance,
the switch statement looks pretty symmetric, the SUSPEND/RESUME
pair is not: the suspend case comes along snd_pcm_suspend_all(),
which for fsl/imx-pcm-fiq is called only at snd_soc_suspend(),
but the resume case originates straight from the SNDRV_PCM_IOCTL_RESUME.
This way userland may provoke an unbalanced resume, which might cause
the fiq_enable counter to increase and never return to zero again,
so eventually imx_pcm_fiq is never disabled.
Simply removing the fiq_enable will solve the problem, as long as
one never goes play and capture game simultaneously, but beware
trying both at once, the early TRIGGER_STOP will cut off the other
activity prematurely. So now playing and capturing is scrutinized
separately, instead of by counting.

snd_hda_codec_reset() is called either in resetting the whole setup at

There's also no reason to assume that we can't write more data

a stream in paused state will still report the buffer
availability from poll(). It is up to the user process to
manage its state so that it knows whether it is paused or not.

component is not supported - 255), but no checking is performed since
this was not mentioned in the AMD HDA verbs specification.
Check that the latencies are valid before using them, and add a comment
