9f8a7658bc ALSA: timer: Fix zero-division by continue of uninitialized instance
When a user timer instance is continued without the explicit start
beforehand, the system gets eventually zero-division error like:

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.

f3f6c61452 ALSA: pcm: Fix avail to return error if stream is suspended
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
snd_pcm_avail to return -ESTRPIPE.

94ae3ce189 ASoC: Intel: Atom: fix IOSF_MBI dependency
fix issue reported by 0-Day with randconfig

The commit a68bc0d43e
("ASoC: Intel: Atom: auto-detection of Baytrail-CR")
added a dependency on IOSF_MBI. The code used the IS_ENABLED macro
to check for this dependency but this is not enough in case the SST
driver is built-in. This could be fixed with IS_REACHABLE but
Baytrail-CR would not be detected depending on combinations of options

Add dependency in Kconfig to solve this for good

Theta/lambda is used to give the fractional portion of the FLL
frequency multiplication. When the synchroniser is active the
reference path lambda value is hard coded in the hardware to
65536. This patch corrects the handling of theta such that it
is scaled to match this denominator, when the synchroniser is
active.

    ==================================================================

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.

38d16f7916 ASoC: rt5659: Enable IRQ output for GPIO1 pin
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

a3930ed060 ASoC: dapm: Fix kcontrol creation for output driver widget
Commit d88429a695 ("ASoC: dapm: Add output driver widget") added
the snd_soc_dapm_out_drv ID for the output driver widget, which is
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
in dapm_create_or_share_kcontrol, since they are essentially the same.

the following code gets executed:

    *data = kzalloc(block->size, GFP_KERNEL);
    memcpy(data, (void *) block->data, block->size);

The memcpy() call overwrites the content of the *data pointer instead of
filling the newly-allocated memory (which pointer is hold by *data).
Fix this by merging kzalloc+memcpy into a single kmemdup() call.

6b1ca4bcad ALSA: fireworks: accessing to user space outside spinlock
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

The problem happens when you call ioctl(SNDRV_TIMER_IOCTL_CONTINUE) on a
completely new/unused timer -- it will have ->sticks == 0, which causes a
divide by 0 in snd_hrtimer_callback().

The below models were developed with a cooperation by Yamaha and Terratec.
 - Yamaha GO 44/Terratec PHASE 24 FW
 - Yamaha GO 46/Terratec PHASE X24 FW

They have the same configurations, thus it's better to unify corresponding
codes.

This commit merges them to reduce the amount of maintained codes.

To use it as more open driver, rsrc-card will be renamed to

it is based on simple-card driver.
To use it as more open driver, rsrc-card will be renamed to
simple-scu-card. In order to easy patch review, as 2nd step,
this patch adds new compatible "simple-scu-audio-card";

rcar-card used specific property, not "simple-audio-card",
but it should be now. Actually, rsrc-card is upstreamed driver,
but noone is using it on upstream. The user is only local,
and it is only me. Thus, there is no compatible break by this patch.
This patch uses "simple-audio-card" prefix.
And it removes rcar-card specifix compatible too.

8ce8eb601c ALSA: seq: add an alternative way to handle ioctl requests
ALSA sequencer is designed with two types of clients; application and
kernel. Operations for each ioctl command should handle data in both of
user space and kernel space, while current implementation just allows them
to handle data in user space. Data in kernel space is handled with change
of address limit of running tasks.

This commit adds a new table to map ioctl commands to corresponding
functions. The functions get data in kernel space. Helper functions to
operate kernel and application clients seek entries from the table.
Especially, the helper function for application is responsible for coping
from user space to kernel space or vise versa.

For some reason the IPC interrupt index is also modified from

a52ff34e5e ALSA: hda - Manage power well properly for resume
For SKL and later Intel chips, we control the power well per codec
basis via link_power callback since the commit [03b135cebc: 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
[033ea349a7: ALSA: hda - Fix Skylake codec timeout] becomes
superfluous, as snd_hdac_display_power() already does it.  So we can
clean it up together.
