The default EAPD control uses verb command to control EAPD. Some codec
does not have verb command for EAPD. It needs to control by hidden
register.
This update will avoid wrong behavior for some codec. This patch will
fix double setup for EAPD. It just needs to turn on by one site for
verb command or hidden register controlled.
Detailed changes:
- alc889_coef_init() is replaced with alc_update_coef_idx() with a
correct COEF value.
- for ALC262, ALC887 and ALC900, the EAPD setup via the hidden
register is removed because this rather conflicts with the EAPD verb
setup.
- For ALC888-VC, also the hidden register access is removed in
alc888_coef_init().
- Remove the dead #if 0 code for ALC267/ALC268.

These three HP machines all have the same pin config, so we can

These HP machines needs GPIO 4 low to enable the headphone amplifier.
In addition, we still need to control LEDs via vref and GPIO.

es1968_measure_clock uses struct timeval, which on 32-bit systems will overflow
in 2038, leading to incorrect interpretation of time.This patch changes the
function to use ktime_t instead of struct timeval, which implies:
- no y2038: ktime_t uses a 64-bit datatype explicitly.
- efficent subtraction: The earlier version computes the difference in usecs
while dealing with secs and nsecs. It requires checks to see if the nsecs of
stop is less than start. This patch uses a direct subtract of ktime_t and
converts to usecs.
- use of monotonic clock (ktime_get) over real time (do_gettimeofday),
which simplifies timekeeping, as it does not have to deal with cases
where stop_time is less than start_time.

CMI8888 shows the stuttering playback when the snooping is disabled
on the audio buffer. Meanwhile, we've got reports that CORB/RIRB
doesn't work in the snooped mode. So, as a compromise, disable the
snoop only for CORB/RIRB and enable the snoop for the stream buffers.
The resultant patch became a bit ugly, unfortunately, but we still can
live with it.

This patch is concerned with migrating the time variables in the pcxhr
module found in the sound driver. The changes are concerend with the
y2038 problem where timeval will overflow in the year 2038. ktime_t
was used instead of timeval to get the wall time. The difference
is displayed now in nanoseconds instead of microseconds.

request_module() handles the printf style arguments, so we don't have
to render strings in the caller side. Not only it reduces the
unnecessary temporary string buffer, it's even safer from the security
POV.

Without this terminating entry, the pin matching would continue
across random memory until a zero or a non-matching entry was found.
The result being that in some cases, the pin quirk would not be
applied correctly.

this is a series of patches to just convert the plain info callback
for enum ctl elements to snd_ctl_elem_info(). Also, it includes the
extension of snd_ctl_elem_info(), for catching the unexpected string
cut-off and handling the zero items.
As of now the pointer to struct dai is not being used anywhere in the
function. So it is safe to remove the variable.
If we are ever doing anything with the container_of(daio, struct dai, daio),
then at that time we can again add the variable.

In case there are speakers or headphones as well, anything that only
covers the line out should not be labelled "PCM". Let's name it
"Line Out" instead for clarity.

In the scenario where there is one "Line Out", one "Speaker" and one
"Headphone", and there are only two DACs, two outputs will share a DAC.
Currently any mixer on such a DAC will get the "PCM" name, which is
misleading. Instead use "Headphone+LO" or "Speaker+LO" to better
specify what the volume actually controls.
