While line6_probe() may kick off URB for a control MIDI endpoint, the
function doesn't clean up it properly at its error path. This results
in a leftover URB action that is eventually triggered later and causes
an Oops like:

The event handler in the virmidi sequencer code takes a read-lock for
the linked list traverse, while it's calling snd_seq_dump_var_event()
in the loop. The latter function may expand the user-space data
depending on the event type. It eventually invokes copy_from_user(),
which might be a potential dead-lock.
The sequencer core guarantees that the user-space data is passed only
with atomic=0 argument, but snd_virmidi_dev_receive_event() ignores it
and always takes read-lock(). For avoiding the problem above, this
patch introduces rwsem for non-atomic case, while keeping rwlock for
atomic case.
Also while we're at it: the superfluous irq flags is dropped in
snd_virmidi_input_open().

The usx2y driver allocates the stream read/write buffers in continuous

warning messages with a stack trace like:

It may confuse user as if it were any serious error, although this is
no fatal error and the driver handles the error case gracefully.
Since the driver has already some sanity check of the given size (128
and 256 pages), it can't pass any crazy value. So it's merely page
fragmentation.
This patch adds __GFP_NOWARN to each caller for suppressing such
kernel warnings. The original issue was spotted by syzkaller.

This reverts commit 275353bb68 to fix a regression which can abort
'alsactl' program in alsa-utils due to assertion in alsa-lib.
alsactl: control.c:2513: snd_ctl_elem_value_get_integer: Assertion `idx < sizeof(obj->value.integer.value) / sizeof(obj->value.integer.value[0])' failed.
alsactl: control.c:2976: snd_ctl_elem_value_get_integer: Assertion `idx < ARRAY_SIZE(obj->value.integer.value)' failed.
This commit is a band-aid. In a point of usage of ALSA control interface,
the drivers still bring an issue that they prevent userspace applications
to have a consistent way to parse each levels of the dimension information
via ALSA control interface.
Let me investigate this issue. Current implementation of the drivers
have three control element sets with dimension information:
* 'Monitor Mixer Volume' (type: integer)
* 'VMixer Volume' (type: integer)
* 'VU-meters' (type: boolean)
Although the number of elements named as 'Monitor Mixer Volume' differs
depending on drivers in this group, it can be calculated by macros
defined by each driver (= (BX_NUM - BX_ANALOG_IN) * BX_ANALOG_IN). Each
of the elements has one member for value and has dimension information
with 2 levels (= BX_ANALOG_IN * (BX_NUM - BX_ANALOG_IN)). For these
elements, userspace applications are expected to handle the dimension
information so that all of the elements construct a matrix where the
number of rows and columns are represented by the dimension information.
The same way is applied to elements named as 'VMixer Volume'. The number
of these elements can also be calculated by macros defined by each
drivers (= PX_ANALOG_IN * BX_ANALOG_IN). Each of the element has one
member for value and has dimension information with 2 levels
(= BX_ANALOG_IN * PX_ANALOG_IN). All of the elements construct a matrix
with the dimension information.
An element named as 'VU-meters' gets a different way in a point of
dimension information. The element includes 96 members for value. The
element has dimension information with 3 levels (= 3 or 2 * 16 * 2). For
this element, userspace applications are expected to handle the dimension
information so that all of the members for value construct a matrix
where the number of rows and columns are represented by the dimension
information. This is different from the way for the former.
As a summary, the drivers were not designed to produce a consistent way to
parse the dimension information. This makes it hard for general userspace
applications such as amixer to parse the information by a consistent way,
and actually no userspace applications except for 'echomixer' utilize the
dimension information. Additionally, no drivers excluding this group use
the information.
The reverted commit was written based on the latter way. A commit
860c1994a7 ('ALSA: control: add dimension validator for userspace
elements') is written based on the latter way, too. The patch should be
reconsider too in the same time to re-define a consistent way to parse the
dimension information.

On recent Intel platforms (Haswell, Broadwell, Skylake, ApolloLake,
KabyLake, ...), the IEC Coding Type (ICT) bitfield in the Digital
Converter Control #3 needs to be set explicitly for HDMI/DisplayPort
High Bit Rate (HBR) audio playback to work. This was not required in
earlier platforms when HBR was first introduced. The ICT bits are
defined in Section 7.3.3.9 of the HDaudio 1.0a specification.
Since the ICT bitfield was not specified for HDAudio 1.0 devices
(before 2009), we only program it on machines more recent than
Haswell.
We tested that this fix is not needed on Baytrail-I (MinnowBoard
Turbot) and believe by extension it also does not apply to Braswell.

The hm->h.size is intended to hold the actual size of the hm struct
that is copied from userspace and should always be <= sizeof(*hm).
However, after copy_from_user(hm, puhm, hm->h.size), since userspace
process has full control over the memory region pointed by puhm, it is
possible that the value of hm->h.size is different from what is fetched-in
previously (get_user(hm->h.size, (u16 __user *)puhm)). In other words,
hm->h.size is overriden and the relation between hm->h.size and the hm
struct is broken.
This patch proposes to use a seperate variable, msg_size, to hold
the value of the first fetch and override hm->h.size to msg_size
after the second fetch to maintain the relation.

For wake on voice use case, we need to copy data from DSP buffer
to PCM stream when system wakes up by voice. However the edge
triggered IRQ could be missed when system wakes up, in that case
the irq function will not be called. Fix that by checking the irq
status bit and schedule data copy accordingly.

ALSA sequencer core has a mechanism to load the enumerated devices
automatically, and it's performed in an off-load work. This seems
causing some race when a sequencer is removed while the pending
autoload work is running. As syzkaller spotted, it may lead to some
use-after-free:

We have touched quite a lot of files but with fewer changes at this
cycle; as you can see, most of changes are trivial fixes, especially
constification patches. Among the massive attacks by constification
gangs, we had a few core changes (mostly for ASoC core), as well the
fixes and the updates by major vendors. Some highlights are below:
ALSA core:
- Fix possible races in control API user-TLV codes
- Small cleanup of PCM core
ASoC:
- Continued work for componentization; still half-baked, but we're
certainly progressing
- Use of devres for jack detection GPIOs, rather as a cleanup
- Jack detection support for Qualcomm MSM8916

The ADC in the ADAU1361 (and possibly other Analog Devices codecs)
exhibits a cyclic variation in the noise floor (in our test setup between
-87 and -93 dB), a new value being attained within this range whenever a
new capture stream is started. The cycle repeats after about 10 or 11
restarts.
The workaround recommended by the manufacturer is to toggle the ADOSR bit
in the Converter Control 0 register each time a new capture stream is
started.
I have verified that the patch fixes this problem on the ADAU1361, and
according to the manufacturer toggling the bit in question in this manner
will at least have no detrimental effect on other chips served by this
driver.

This is quite a large release by volume of patches and diff, a lot of
that is mechanical cleanup patches but it's great to also see a range of
vendors actively working on adding new features and fixing issues in
their drivers. Intel and Realtek have been especially active here.
- Continued work towards moving everything to the component model from
Morimoto-san.
- Use of devres for jack detection GPIOs, eliminating some potential
resource leaks.
- Jack detection support for Qualcomm MSM8916.
- Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake
systems with RT5663, Realtek RT274, TI TLV320AIC32x6 and Wolfson

Some ioctl functions are implemented individually for both playback
and capture streams although most of the codes are identical with just
a few different stream-specific function calls. This patch unifies
these places, removes the superfluous trivial check and flattens the
call paths as a cleanup. Meanwhile, for better readability, some
codes (e.g. xfer ioctls or forward/rewind ioctls) are factored out as
functions.

Currently we're taking power_lock at each card component for assuring
the power-up sequence, but it doesn't help anything in the
implementation at the moment: it just serializes unnecessarily the
callers, but it doesn't protect about the power state change itself.
It used to have some usefulness in the early days where we managed the
PM manually. But now the suspend/resume core procedure is beyond our
hands, and power_lock lost its meaning.
This patch drops the power_lock from allover the places.
There shouldn't be any issues by this change, as it's no helper
regarding the power state change. Rather we'll get better performance
by removing the serialization; which is the only slight concern of any
behavior change, but it can't be a showstopper, after all.

PCM OSS emulation issues the drain ioctl without power lock. It used
to work in the earlier kernels as the power lock was taken inside
snd_pcm_drain() itself. But since 68b4acd322 ("ALSA: pcm: Apply
power lock globally to common ioctls"), the power lock is taken
outside the function. Due to that change, the call via OSS emulation
leads to the unbalanced power lock, thus it deadlocks.
As a quick fix, just take the power lock before snd_pcm_drain() call
for OSS emulation path. A better cleanup will follow later.

Setting the PLL involves the calculation of a fixed point ratio
with 4 decimal digits fraction, referred to as "J.D". The
fraction "D" is stored separately from the integer part "J"
and is limited to 0..9999.
The current algorithm uses integer registers to calculate the
fraction part, but failed to compensate for rounding errors,
resulting in values larger than 9999 for the fraction part
occasionally, e.g. for 44.1kHz audio rate and pll_clkin =
3763400 it would set J to 11 and D to 10002, which will at
best result in wrong pitch.
The critical part is the "pll_clkin / 10000", which would be
ok with real numbers, but using integer arithmetic the rounding
decreases the divisor, thus increasing the final quotient.
The issue is solved by linear interpolation over the reciprocal
function between the two adjacent points with integer divisor,
i.e. pll_clkin / 10000 and pll_clkin / 10000 + 1, and doing
all rounding to the lower result.

Not all devices with ACPI and this combination of sound devices will

[ More background note:
the commit a36afb0ab6 ("ASoC: rt5677: Introduce proper table...")
moved the i2c ID probed via ACPI ("RT5677CE:00") to a proper
acpi_device_id table. Although the action itself is correct per se,
the overseen issue is the reference id->driver_data at
rt5677_i2c_probe() for retrieving the corresponding chip model for
the given id. Since id=NULL is passed for ACPI matching case, we get
an Oops now.
We already have queued more fixes for 4.14 and they already address
the issue, but they are bigger changes that aren't preferable for the
late 4.13-rc stage. So, this patch just papers over the bug as a
once-off quick fix for a particular ACPI matching. -- tiwai ]

In a design of ALSA control core, a set of elements is represented by
'struct snd_kcontrol' to share common attributes. The set of elements
shares TLV (Type-Length-Value) data, too.
On the other hand, in ALSA control interface/protocol for applications,
a TLV operation is committed to an element. Totally, the operation can
have sub-effect to the other elements in the set. For example, TLV_WRITE
operation is expected to change TLV data, which returns to applications.
Applications attempt to change the TLV data per element, but in the above
design, they can effect to elements in the same set.
As a default, ALSA control core has no implementation except for TLV_READ
operation. Thus, the above design looks to have no issue. However, in
kernel APIs of ALSA control component, developers can program a handler
for any request of the TLV operation. Therefore, for elements in a set
which has the handler, applications can commit TLV_WRITE and TLV_COMMAND
requests.
For the above scenario, ALSA control core assist notification. When the
handler returns positive value, the core queueing an event for a requested
element. However, this includes design defects that the event is not
queued for the other element in a set. Actually, developers can program
the handlers to keep per-element TLV data, but it depends on each driver.
As of v4.13-rc6, there's no driver in tree to utilize the notification,
except for user-defined element set. This commit delegates the notification
into each driver to prevent developers from the design defects.

decrements the dsp core ref count and ref count becomes unbalanced.
This results in dsp core powered up in further runtime suspend/resume
cycles and never powered down.
So increment the ref count before dsp core powerup and for any failure,

Dell laptops have another LED for mic-mute in addition to the master
mute. The former is tied with the capture switch (in a reverse way)
while the latter is tied with the master playback switch. We already
have an enum control to change the behavior for the master mute LED in
different ways, e.g. keeping always off or turning off at mute. But,
the mic-mute LED has no such management but its behavior is
hard-coded.
This patch implements an enum control to change the mic-mute LED
behavior like what we have for the master mute LED. The ctl provides
four modes: keep-on, keep-off, follow-capture and follow-mute. The
default mode is the last one, follow-mute, which follows the capture
mute, i.e. LED turning on when the capture is off, and turning off
when the capture is active.

The 'dmic-delay' property name is different with the dt-binding.
So correct it with 'dmic-wakeup-delay-ms'.

STAudio ADCIII has the same SSID as Hoontech STDSP24, but requires a
slightly different configuration. This patch allows user to choose
this model via model=staudio option to set the proper configuration
for the board.

When user tries to replace the user-defined control TLV, the kernel
checks the change of its content via memcmp(). The problem is that
the kernel passes the return value from memcmp() as is. memcmp()
gives a non-zero negative value depending on the comparison result,
and this shall be recognized as an error code.
The patch covers that corner-case, return 1 properly for the changed
TLV.

RT5670 codec driver and its machine driver for Intel CHT assume the
implicit GPIO mapping on the index 0 while BIOS on most devices don't
provide it. The recent commit f10e4bf663 ("gpio: acpi: Even more
tighten up ACPI GPIO lookups") restricts such cases and it resulted in
a regression where the headset jack setup fails like:
rt5670 i2c-10EC5672:00: ASoC: Cannot get gpio at index 0: -2
rt5670 i2c-10EC5672:00: Adding jack GPIO failed
For fixing this, we need to provide the GPIO mapping explicitly in the
machine driver. Also this patch corrects the string to be passed to
gpiolib to match with the pre-given mapping, too.

Currently we are searching dai name in snd_soc_find_dai, which could
either be dai driver name or component device name(for legacy naming).
Allow searching dai driver name in snd_soc_find_dai too, so that we can
use dai driver name to find legacy naming dais.

Let's be lazy -- this patch adds the devres code to
snd_soc_jack_add_gpios() for releasing the gpio resources at device
removal automagically. After this patch, you don't have to call
snd_soc_jack_free_gpios() manually as long as it's managed from the
machine driver.
What about the gpios assigned in other levels? Well, you might still
need to free the resources manually, depending on how the component
unbind works.

These headsets reports a lot of: cannot set freq 44100 to ep 0x81
and need a small delay between sample rate settings, just like
Zoom R16/24. Add both headsets to the Zoom R16/24 quirk for
a 1 ms delay between control msgs.
