The USB completion callback does not disable interrupts while acquiring
the lock. We want to remove the local_irq_disable() invocation from
__usb_hcd_giveback_urb() and therefore it is required for the callback
handler to disable the interrupts while acquiring the lock.
The callback may be invoked either in IRQ or BH context depending on the
USB host controller.
Use the _irqsave() variant of the locking primitives.

Both calls to of_find_node_by_name() and of_get_next_child() return a
node pointer with refcount incremented thus it must be explicidly
decremented here after the last usage. As we are assured to have a
refcounted np either from the initial
of_find_node_by_name(NULL, name); or from the of_get_next_child(gpio, np)
in the while loop if we reached the error code path below, an
x of_node_put(np) is needed.

When i915 component binding fails, it means that HDMI isn't applicable
anyway. Although the probe with the generic HDMI parser would still
work, it's essentially useless, hence better to be left unbound.
This patch mimics the probe_id field at failing the i915 component
binding so that the generic HDMI won't be bound after that.

The in_pm atomic in hdac_device is an important field used as a flag
as well as a refcount for PM. The existing snd_hdac_power_up/down
helpers already refer to it in the HD-audio core code, while the code
to actually setting the value (atomic_inc() / _dec()) is open-coded in
HDA legacy side, which is hard to find.
This patch adds the helper functions to set/reset the in_pm counter to
HDA core and use them in HDA legacy side, for making it clearer who /
where the PM is managed.
There is no functional changes, just code refactoring.

Currently patch_alc269() calls the fixup with HDA_FIXUP_ACT_PRE_PROBE
before setting up the codec model-specific setups (e.g. setting
codec_variant or mixer_nid setup). This is rather confusing as others
do call the *_PRE_PROBE fixup after such a setup. Due to this
disorder, we have to override spec->shutup not at the usual
HDA_FIXUP_ACT_PRE_PROBE but the unusual HDA_FIXUP_ACT_PROBE time.
This patch corrects the fixup call orders in patch_alc269(), and also
corrects the action to set up spec->shutup accordingly.
No functional changes but just refactoring.

In this patch, the remaining static init verbs in VIA codec driver are
converted to the standard snd_hda_add_verbs() calls. The conversion
is straightforward, but one change to be noted is the place of calls:
since these verbs are supposed to be executed at the beginning of the
init / resume procedure, we need to add snd_hda_add_verbs() calls
before calling the other parsers.
This is merely a cleanup, no functional changes.

This patch replaces the control element creations in VIA codec driver
with the standard snd_hda_gen_add_kctl() calls as a cleanup. There
are two major fields targeted by this patch: the beep controls and
static init controls.
The former is converted just like other codec drivers do. The
spec->beep_amp field can be eliminated by this change as well.
The latter, static init controls, are replaced simply with explicit
snd_hda_gen_add_kctl() calls.
After these conversions, via_build_controls() becomes superfluous and
replaced with snd_hda_gen_build_controls(), too.

This patch moves the mixer creation code in Cirrus codec driver from
its own build_controls callback to snd_hda_gen_add_kctl() for

becomes identical with snd_hda_gen_build_controls().

Like the previous commit for Realtek codec, the similar cleanup work
can be applied to Conexant codec, too. A slight difference is that
the call of cx_auto_parse_beep() is moved after
snd_hda_gen_parse_auto_config(). It's not strictly needed, but it'd
be good to make the creation of such beep mixers at the end, which
matches with the former situation.
Along with this conversion, cx_auto_build_controls() becomes just
calling snd_hda_gen_build_controls(), so it's simply replaced with
snd_hda_gen_build_controls.

In the Realtek codec driver, we used to build kctl elements for beep
mixer in the own build_controls callback. This is an open-code and
can be covered by the standard feature of the generic parser with
snd_hda_gen_add_kctl() instead.
Also, after the conversion, spec->beep_amp becomes superfluous; hence
it's removed along with the conversion.

The beep mixer controls are the only remaining stuff that uses
spec->mixers[] array, and they can be well converted to the standard
helper in the generic parser, snd_hda_gen_add_kctl().

Dell XPS13 has multi-step fixups, and one of them
(ALC288_FIXUP_DELL_XPS_13_GPIO6) corresponds to the management of GPIO
bit6 (0x40). It used to be a static init verbs (to turn *off* the
bit6).
In this patch, we convert it as the gpio_mask and gpio_dir
initializations folded in the existing fixup function. With this
change, ALC288_FIXUP_DELL_XPS_13_GPIO6 becomes superfluous, thus it's
removed.

Currently the GPIO bits are managed by individual verbs in some cases
while toggled dynamically in other cases. For simplifying the GPIO
management, define the GPIO mask, dir and data bits in alc_spec

this patch replaces the static verbs that are used at initialization

Some devices have the overrides of spec->init_amp at
HDA_FIXUP_ACT_PROBE just because alc_ssid_check() gives the
false-positive values from the SSID.
For more consistent behavior, define the logic in the following way:
- Define ALC_INIT_UNDEFINED as the default value before calling
alc_ssid_check()
- Each fixup may set up spec->init_amp with another value at
HDA_FIXUP_ACT_PRE_PROBE
- At detection, check whether spec->init_amp is ALC_INIT_UNDEFINED or
not; if it's different, we skip the detection
Also, it turned out that ASUS TX300 requires the spec->init_amp
override, too; currently it ignores the GPIO bits implicitly by its
static init verb, but this will be changed in the later patchset.

This commit adds support for MOTU Traveler, launched in 2005, discontinued
quite before. As a result, transmission of PCM frame and MIDI messages is
available via ALSA PCM and RawMIDI/Sequencer interfaces.
This model supports sampling transmission frequency up to 192.0 kHz, and
AES/EBU on XLR interface and ADAT on optical interface. Unlike
Motu 828MkII, Windows driver can switch fetching mode for DSP, like
mute/unmute feature.
Although this commit enables high sampling transmission frequency, actual
sound from this model is not good. As long as I tested, it's silence at
176.4 kHz, and it includes hissing noise at 192.0 kHz. In my opinion, as I
reported at 3526ce7f9ba7 ('ALSA: firewire-motu: add MOTU specific protocol
layer'), timestamping on source packet header (SPH) may not still be good
for this model as well.

For MOTU protocol version 2, this driver arranges the number of data
chunks to align chunks to quadlet data channel. However, MOTU Traveler
has padding bytes in the end of data block at high clock mode.
This commit removes the arrangement. Fortunately, at low and middle clock
mode, supported model for v2 protocol (828mkII) gets no influence from this
change because all of combination for data chunks are just aligned to
quadlet data channel.

In MOTU firewire protocol, data block consists of 24 bit data chunks except
for one quadlet for source packet header (SPH). The number of data chunk in
a data block is different between three clock modes; low, middle and high.
When unit supports ADAT on optical interface, the data block includes some
chunks for ADAT channels. These ADAT chunks are unavailable at high mode.
This driver has local functions to calculate the number of ADAT chunks. But
They uses stack for three clock modes. This is useless for higher mode.

The get_seconds() function is deprecated because it truncates the

The commentary says to use various parameters, and lays out what
the mapping is... The code used a 32KHz rate when the comment
says that it needs to use a 48KHz rate. And this has been the
case since day one.
On the Alienware M17x R4, the DMic used to have exceptionally quiet
pickup and a lot of noise. Changing the data rate fixes both of
these issues.
Searching the kernel bug tracker for ca0132-related issues shows no
mention of this being an issue for other hardware, and I have no
other hardware to test with, so a quirk is used to limit the effect
to just the M17x R4.
