The Chromebook Pixel 2015 uses this codec with the ACPI ID RT5677CE, but
does not use the standard DT property names so add a new function to
parse the codec properties from these ACPI properties.
Also, the GPIOs are only available by index, so we need to register a
mapping to allow machine drivers to access the GPIOs by name.

Currently the DSP loading is split into two widgets, the preloader that
is a snd_soc_dapm_dai_link widget which starts a thread to download
the firmware, and the DSP itself which is a snd_soc_dapm_out_drv and
synchronises the thread back in to the DAPM sequence. This allows the
firmware download to be overlapped with the rest of the path bring up.
The use of a snd_soc_dapm_dai_link widget requires the preloader to be part
of the audio path in DAPM, really a supply widget is a better fit for the
preloader. The preloader is something that needs to be done for the DSP to
function, not a part of the audio path itself.
This change makes the DSP preloader widget a supply widget, which as well
as probably being a better fit will also make it much simpler to power up
the preloader widget to trigger firmware download to the core independently
of the audio path coming up.

Currently SYSCLK is attached to every compressed DAI as this follows the
pattern of attaching clocks to the chips inputs and outputs, however, it is
really the DSP that requires the clock here. As firmware download can be a
significant part of the path startup time for these devices occasionally it
would be desirable to download the firmware in advance of the path being
brought up.
To help facilitate this early firmware loading this patch attaches the
SYSCLK to the DSP preloader widget. This also saves us adding a new route
to SYSCLK every time a new compressed DAI is created.

As part of the work to download firmware before the audio path is brought
up the DSP will be put into a low power state between downloading firmware
to the core and starting it running. This will mean that the firmware ALSA
controls are not accessible in the hardware during this period of time.
To prepare for this change we gate access to the hardware in the ALSA
control handlers on the DSP being running rather than simply booted and
move the synchronisation of the control caches out of the preloader delayed
work and into the main DAPM thread after the DSP will have been brought out
of its low power state.

Currently the wm_adsp driver has a flag that indicates the DSP is
"running", this flag is used to gate access to the hardware. However this
flag is actually set in the firmware download thread after the firmware has
been downloaded, but this is before the core is actually started running,
so really it currently indicates that the core has been booted and is
perhaps running.
This patch clearly separates out the concepts of booted (firmware is
downloaded) and running (code is executing on the DSP) within the wm_adsp
driver.

Driver needs to send unique module instance id to firmware while
creating the module and uses this id to communicate with DSP for setting
parameters while audio use case is ongoing.
But, we have upper bound of instance ID. The current IDs are coming from
topology but it doesn't know the upper bound and can't assign unique
id's subject to upper bounds as we can create a big graph but not all
parts running at same time.
This patch adds a 128bit unique id management routines which are built
on top of ffz() for faster implementation. Unfortunately ffz() works on
32bits values, so additional code is added on top of ffz() to create a
128bit unique id.

The DragonFly quirk added in 42e3121d90 ("ALSA: usb-audio: Add a more
accurate volume quirk for AudioQuest DragonFly") applies a custom dB map
on the volume control when its range is reported as 0..50 (0 .. 0.2dB).
However, there exists at least one other variant (hw v1.0c, as opposed
to the tested v1.2) which reports a different non-sensical volume range
(0..53) and the custom map is therefore not applied for that device.
This results in all of the volume change appearing close to 100% on
mixer UIs that utilize the dB TLV information.
Add a fallback case where no dB TLV is reported at all if the control
range is not 0..50 but still 0..N where N <= 1000 (3.9 dB). Also
restrict the quirk to only apply to the volume control as there is also
a mute control which would match the check otherwise.

NO_IRQ has been == 0 on powerpc for just over ten years (since commit
0ebfff1491 ("[POWERPC] Add new interrupt mapping core and change
platforms to use it")). It's also 0 on most other arches.
Although it's fairly harmless, every now and then it causes confusion
when a driver is built on powerpc and another arch which doesn't define
NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least
some of which are to work around that problem.
So we'd like to remove it. This is fairly trivial in the arch code, we
just convert:
if (irq == NO_IRQ) to if (!irq)
if (irq != NO_IRQ) to if (irq)
irq = NO_IRQ; to irq = 0;
return NO_IRQ; to return 0;
And a few other odd cases as well.
At least for now we keep the #define NO_IRQ, because there is driver
code that uses NO_IRQ and the fixes to remove those will go via other
trees.
Note we also change some occurrences in PPC sound drivers, drivers/ps3,
and drivers/macintosh.

The workqueue "dac33_wq" queues a single work item &dac33->work and
hence doesn't require ordering. Also, it is not being used on a memory
reclaim path. Hence, it has been converted to use system_wq.
System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.
The work item has been flushed in dac33_soc_remove to ensure that
there are no pending tasks while disconnecting the driver.

Currently the driver code assumes that MCLK will be present during
the procedure, or if it has control of MCLK then it can make sure
it's enabled. Some platforms however do not provide MCLK to the
driver in this way, and will not leave MCLK enabled when Codec is
in STANDBY state.
This patch adds support for the HP detect procedure when running
from the device's internal oscillator, to ensure all platforms
can make use of this feature correctly.

Realtek codec driver expects an implicit rule where either the codec
SSID or the pincfg NID 0x1d contains the some information encoded in
some bits. One of the expected information is there is the
availability of PC beep, and the driver doesn't build up the PC beep
control if this is *supposed* to be disabled there.
Meanwhile, Lenovo doesn't seem to follow this requirement (yes it's
non-standard after all), and the BIOS sets just the normal SSID and
the pincfg values. This resulted in the lack of PC beep on a few
machines, purely with a lucky or unlucky number. It didn't bother
most people, but some people still demand the PC beep, as found in bug
reports.
This patch just adds the fixup chain to Lenovo machines to skip the
SKU checks. Then the beep control will show up in the mixer, and user
can still decide to enable / disable it via the standard mixer
interface.

When a seq-virmidi driver is initialized, it registers a rawmidi
instance with its callback to create an associated seq kernel client.
Currently it's done throughly in rawmidi's register_mutex context.
Recently it was found that this may lead to a deadlock another rawmidi
device that is being attached with the sequencer is accessed, as both
open with the same register_mutex. This was actually triggered by
syzkaller, as Dmitry Vyukov reported:

The fix is to simply move the registration parts in
snd_rawmidi_dev_register() to the outside of the register_mutex lock.
The lock is needed only to manage the linked list, and it's not
necessarily to cover the whole initialization process.

Although a similar issue was spotted and a fix patch was merged in
commit [6b760bb2c6: ALSA: timer: fix division by zero after
SNDRV_TIMER_IOCTL_CONTINUE], it seems covering only a part of
iceberg.
In this patch, we fix the issue a bit more drastically. Basically the
continue of an uninitialized timer is supposed to be a fresh start, so
we do it for user timers. For the direct snd_timer_continue() call,
there is no way to pass the initial tick value, so we kick out for the
uninitialized case.

When the stream is in suspended state some applications wait
on "Stream Pipe Error" in response to snd_pcm_avail call to
resume the stream.
In the current implementation snd_pcm_avail() returns zero
when the stream is in suspended state. This causes application
to enter in infinite loop for frames to be available.
"Stream pipe Error" code is getting returned for read/write
call when the stream is in suspended state. Similarly update

There are a couple of problems that I can see:
- ioctl(SNDRV_TIMER_IOCTL_SELECT), which potentially sets
tu->queue/tu->tqueue to NULL on memory allocation failure, so read()
would get a NULL pointer dereference like the above splat
- the same ioctl() can free tu->queue/to->tqueue which means read()
could potentially see (and dereference) the freed pointer
We can fix both by taking the ioctl_lock mutex when dereferencing
->queue/->tqueue, since that's always held over all the ioctl() code.
Just looking at the code I find it likely that there are more problems
here such as tu->qhead pointing outside the buffer if the size is
changed concurrently using SNDRV_TIMER_IOCTL_PARAMS.

Since it's possible to have an IRQ without enabling JD3, the
GPIO1 pin then would remain its default GPIO function which
is set as an input direction (seeing from rt5659). Meanwhile,
CPU would also listen this connection via its own GPIO input:
[input] [input]
CPU GPIO <--------> RT5659 GPIO1
The result for the IRQ on the CPU side will be unexpectable.
So this patch enables the IRQ output for GPIO1 pin any way
as long as there's an IRQ assigned from platform data or DT:
[input] [IRQ output]
CPU GPIO <--------< RT5659 GPIO1

Commit d88429a695 ("ASoC: dapm: Add output driver widget") added

the same as the PGA widget, with a later power sequence number.
Commit 19a2557b76 ("ASoC: dapm: Add kcontrol support for PGAs")
then added kcontrol support for PGA widgets, but failed to account
for output driver widgets. Attempts to use kcontrols with output
driver widgets result in silent failures, with the developer having
little idea about what went on.
Add snd_soc_dapm_out_drv to the switch/case block under snd_soc_dapm_pga

The memcpy() call overwrites the content of the *data pointer instead of

In hwdep interface of fireworks driver, accessing to user space is in a
critical section with disabled local interrupt. Depending on architecture,
accessing to user space can cause page fault exception. Then local
processor stores machine status and handles the synchronous event. A
handler corresponding to the event can call task scheduler to wait for
preparing pages. In a case of usage of single core processor, the state to
disable local interrupt is worse because it don't handle usual interrupts
from hardware.
