HP Spectre x360 with CX20724 codec has two speaker outputs while the
BIOS sets up only the bottom one (NID 0x17) and disables the top one
(NID 0x1d).
This patch adds a fixup simply defining the proper pincfg for NID 0x1d
so that the top speaker works as is.

We have two new Dell laptop models, they have the same ALC255 pin
definition, but not in the pin quirk table yet, as a result, the
headset microphone can't work. After adding the definition in the
table, the headset microphone works well.

The DragonFly quirk added in 42e3121d90f4 ("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.

The pointer callbacks of ali5451 driver may return the value at the
boundary occasionally, and it results in the kernel warning like
snd_ali5451 0000:00:06.0: BUG: , pos = 16384, buffer size = 16384, period size = 1024
It seems that folding the position offset is enough for fixing the
warning and no ill-effect has been seen by that.

One of the laptops has the codec ALC256 on it, applying the
ALC255_FIXUP_DELL1_MIC_NO_PRESENCE can fix the problem, the rest
of laptops have the codec ALC295 on them, they are similar to machines
with ALC225, applying the ALC269_FIXUP_DELL1_MIC_NO_PRESENCE can fix
the problem.

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:

lock(register_mutex#5);
lock(&grp->list_mutex);

*** DEADLOCK ***
======================================================
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 [6b760bb2c63a: 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.

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.

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.
This commit fixes this bug, performing the accessing outside spinlock. This
commit also gives up counting the number of queued response messages to
simplify ring-buffer management.

There's also one core fix for an issue when unbinding a card which for

For SKL and later Intel chips, we control the power well per codec
basis via link_power callback since the commit [03b135cebc47: ALSA:
hda - remove dependency on i915 power well for SKL].
However, there are a few exceptional cases where the gfx registers are
accessed from the audio driver: namely the wakeup override bit
toggling at (both system and runtime) resume. This seems causing a
kernel warning when accessed during the power well down (and likely
resulting in the bogus register accesses).
This patch puts the proper power up / down sequence around the resume
code so that the wakeup bit is fiddled properly while the power is
up. (The other callback, sync_audio_rate, is used only in the PCM
callback, so it's guaranteed in the power-on.)
Also, by this proper power up/down, the instantaneous flip of wakeup
bit in the resume callback that was introduced by the commit
[033ea349a7cd: ALSA: hda - Fix Skylake codec timeout] becomes
superfluous, as snd_hdac_display_power() already does it. So we can
clean it up together.

In chromium, the following steps will make codec function fail.
\1. plug in headphones, Play music
\2. run "powerd_dbus_suspend"
\3. resume from S3
After resume, the jack detection will restart and make configuration
for the headset. Meanwhile, the playback prepares and starts to work.
The two sequences will conflict and make wrong register configuration.
Originally, the driver adds protection for the case when it finds
the playback is active. But the "powerd_dbus_suspend" command will
close the pcm stream before suspend. Therefore, the driver can't
detect the playback after resume, and the protection not works.
For the issue, the driver raises protection every time after resume.
The protection will release after jack detection and configuration
completes, and then the playback just will goes on.

Pull ARM SoC driver updates from Olof Johansson:
"Driver updates for ARM SoCs.
A slew of changes this release cycle. The reset driver tree, that we
merge through arm-soc for historical reasons, is also sizable this
time around.
Among the changes:
- clps711x: Treewide changes to compatible strings, merged here for simplicity.
- Qualcomm: SCM firmware driver cleanups, move to platform driver
- ux500: Major cleanups, removal of old mach-specific infrastructure.
- Atmel external bus memory driver
- Move of brcmstb platform to the rest of bcm
- PMC driver updates for tegra, various fixes and improvements
- Samsung platform driver updates to support 64-bit Exynos platforms
- Reset controller cleanups moving to devm_reset_controller_register() APIs
- Reset controller driver for Amlogic Meson
- Reset controller driver for Hisilicon hi6220
- ARM SCPI power domain support"
