Pull stream_open conversion from Kirill Smelkov:
- remove unnecessary double nonseekable_open from drivers/char/dtlk.c
as noticed by Pavel Machek while reviewing nonseekable_open ->
stream_open mass conversion.
- the mass conversion patch promised in commit 10dce8af3422 ("fs:
stream_open - opener for stream-like files so that read and write can
run simultaneously without deadlock") and is automatically generated
by running
$ make coccicheck MODE=patch COCCI=scripts/coccinelle/api/stream_open.cocci
I've verified each generated change manually - that it is correct to
convert - and each other nonseekable_open instance left - that it is
either not correct to convert there, or that it is not converted due
to current stream_open.cocci limitations. More details on this in the
patch.
- finally, change VFS to pass ppos=NULL into .read/.write for files
that declare themselves streams. It was suggested by Rasmus Villemoes
and makes sure that if ppos starts to be erroneously used in a stream
file, such bug won't go unnoticed and will produce an oops instead of
creating illusion of position change being taken into account.
Note: this patch does not conflict with "fuse: Add FOPEN_STREAM to
use stream_open()" that will be hopefully coming via FUSE tree,
because fs/fuse/ uses new-style .read_iter/.write_iter, and for these
accessors position is still passed as non-pointer kiocb.ki_pos .

Pull spi updates from Mark Brown:
"One small feature was added this release but the bulk of the diffstat
and the changelog comes from the fact that several older drivers got
some fairly hefty reworks and a couple of new drivers were added:
- Support for detailed control of timing around chip selects from
Sowjanya Komatineni.
- A big set of fixes and imrovements for the Tegra114 driver from
Sowjanya Komatineni.
- A big simplification of the GPIO driver from Andrey Smirnov.
- DMA support and fixes for the Freescale LPSPI driver from Clark
Wang.
- Fixes and optimizations for the bcm2835aux from Martin Sparl.
- New drivers for Mediatek MT7621 (graduated from staging) and Zynq

Enter to close more power control widgets at suspend.
Remove hp_pin check. Add the default pin 0x21 as headphone.
Supported low power consumption, it must do depop procedure when
headset jack was plugged or unplugged.
So, alc225_init() and alc225_shutup() must run delay when headset
jack was plugged or unplugged.
If depop procedure not run with delay, it will have a chance to let
power consumption raise high.

"Remove Mysterious Macro Intended to Obscure Weird Behaviours (mmiowb())
Remove mmiowb() from the kernel memory barrier API and instead, for

MMIO has been performed inside the critical section.
The only relatively recent changes have been addressing review
comments on the documentation, which is in a much better shape thanks
to the efforts of Ben and Ingo.

you could run the coccinelle script yourself, however it's been plain
sailing in linux-next so I've just included the whole lot here to keep

Using scripts/coccinelle/api/stream_open.cocci added in 10dce8af3422
("fs: stream_open - opener for stream-like files so that read and write
can run simultaneously without deadlock"), search and convert to
stream_open all in-kernel nonseekable_open users for which read and
write actually do not depend on ppos and where there is no other methods
in file_operations which assume @offset access.
I've verified each generated change manually - that it is correct to convert -
and each other nonseekable_open instance left - that it is either not correct
to convert there, or that it is not converted due to current stream_open.cocci
limitations. The script also does not convert files that should be valid to
convert, but that currently have .llseek = noop_llseek or generic_file_llseek
for unknown reason despite file being opened with nonseekable_open (e.g.
drivers/input/mousedev.c)
Among cases converted 14 were potentially vulnerable to read vs write deadlock
(see details in 10dce8af3422):

and the rest were just safe to convert to stream_open because their read and
write do not use ppos at all and corresponding file_operations do not
have methods that assume @offset file access(*):

The max98090 driver defines 3 DAPM muxes; one for the right line output
(LINMOD Mux), one for the left headphone mixer source (MIXHPLSEL Mux)
and one for the right headphone mixer source (MIXHPRSEL Mux). The same
bit is used for the mux as well as the DAPM enable, and although the mux
can be correctly configured, after playback has completed, the mux will
be reset during the disable phase. This is preventing the state of these
muxes from being saved and restored correctly on system reboot. Fix this
by marking these muxes as SND_SOC_NOPM.
Note this has been verified this on the Tegra124 Nyan Big which features
the MAX98090 codec.

The current algorithm allows 3 types of transfers, 16bit, 32bit and
burst. According to Realtek, 16bit transfers have a special restriction
in that it is restricted to the memory region of
0x18020000 ~ 0x18021000. This region is the memory location of the I2C
registers. The current algorithm does not uphold this restriction and
therefore fails to complete writes.
Since this has been broken for some time it likely no one is using it.
Better to simply disable the 16 bit writes. This will allow users to
properly load firmware over SPI without data corruption.

On the machines with AMD GPU or Nvidia GPU, we often meet this issue:
after s3, there are 4 HDMI/DP audio devices in the gnome-sound-setting
even there is no any monitors plugged.
When this problem happens, we check the /proc/asound/cardX/eld#N.M, we
will find the monitor_present=1, eld_valid=0.
The root cause is BIOS or GPU driver makes the PRESENCE valid even no
monitor plugged, and of course the driver will not get the valid
eld_data subsequently.
In this situation, we should not report the jack_plugged event, to do
so, let us change the function hdmi_present_sense_via_verbs(). In this
function, it reads the pin_sense via snd_hda_pin_sense(), after
calling this function, the jack_dirty is 0, and before exiting
via_verbs(), we change the shadow pin_sense according to both
monitor_present and eld_valid, then in the snd_hda_jack_report_sync(),
since the jack_dirty is still 0, it will report jack event according
to this modified shadow pin_sense.
After this change, the driver will not report Jack_is_plugged event
through hdmi_present_sense_via_verbs() if monitor_present is 1 and
eld_valid is 0.

The driver will check the monitor presence when resuming from suspend,
starting poll or interrupt triggers. In these 3 situations, the
jack_dirty will be set to 1 first, then the hda_jack.c reads the
pin_sense from register, after reading the register, the jack_dirty
will be set to 0. But hdmi_repoll_work() is enabled in these 3
situations, It will read the pin_sense a couple of times subsequently,
since the jack_dirty is 0 now, It does not read the register anymore,
instead it uses the shadow pin_sense which is read at the first time.
It is meaningless to check the shadow pin_sense a couple of times,
we need to read the register to check the real plugging state, so
we set the jack_dirty to 1 in the hdmi_repoll_work().

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v5.2
This is a pretty huge set of changes, it's been a pretty active release
all round but the big thing with this release is the Sound Open Firmware
changes from Intel, providing another DSP framework for use with the
DSPs in their SoCs. This one works with the firmware of the same name
which is free software (unlike the previous DSP firmwares and framework)
and there has been some interest in adoption by other systems already so
hopefully we will see adoption by other vendors in the future.
Other highlights include:
- Support for MCLK/sample rate ratio setting in the generic cards.
- Support for pin switches in the generic cards.
- A big set of improvements to the TLV320AIC32x4 drivers from Annaliese
McDermond.
- New drivers for Freescale audio mixers, several Intel machines,
several Mediatek machines, Meson G12A, Sound Open Firmware and
Spreadtrum compressed audio and DMA devices.

For Spreadtrum audio platform driver, it need allocate a larger DMA buffer
dynamically to copy audio data between userspace and kernel space, but that
will increase the risk of memory allocation failure especially the system
is under heavy load situation.
To make sure the audio can work in this scenario, we usually reserve one
region of memory to be used as a shared pool of DMA buffers for the
platform component. So add of_reserved_mem_device_init_by_idx() function
to initialize the shared pool of DMA buffers to be used by the platform
component.

On kbl_rt5663_max98927, commit 38a5882e4292
("ASoC: Intel: kbl_rt5663_max98927: Map BTN_0 to KEY_PLAYPAUSE")
This key pair mapping to play/pause when playing Youtube
The Android 3.5mm Headset jack specification mentions that BTN_0 should
be mapped to KEY_MEDIA, but this is less logical than KEY_PLAYPAUSE,
which has much broader userspace support.
For example, the Chrome OS userspace now supports KEY_PLAYPAUSE to toggle
play/pause of videos and audio, but does not handle KEY_MEDIA.
Furthermore, Android itself now supports KEY_PLAYPAUSE equivalently, as the
new USB headset spec requires KEY_PLAYPAUSE for BTN_0.
https://source.android.com/devices/accessories/headset/usb-headset-spec
The same fix is required on Chrome kbl_da7219_max98357a.

The prepare() ioctl for BE dai link gets called both
when the stream is started and when it is resumed from
suspend. SOF uses this ioctl to set the hw params
again only if the stream has been suspended.
When the stream is started, the hw_params ioctl gets called
before prepare() and hw_params is set for the BE dai link.
So the prepare call does not need to do anything further.
When the stream resumes after system suspend, SOF requires
that the hw_params be set again for the BE dai. In order
to determine which streams should set the hw params
during prepare(), an internal flag called "hw_params_upon_resume"
is introduced in struct sof_intel_hda_stream. The flag is set
for hda streams when the sof device suspends and is
cleared after hw_params is set.

When using a shared IRQ between IPC interrupt and stream IOC interrupt,
the interrupt handlers need to check the interrupt source before
scheduling their respective IRQ threads. In the case of IPC handler, it
should check if it is an IPC interrupt before waking up the IPC IRQ
thread.
The IPC IRQ thread, once scheduled, does not need to check the IRQ
source again. So, remove the superfluous check in the thread. Remove the
irq_status field from snd_sof_dev struct also as it is no longer needed.

context
The IPC implementation in SOF requires sending IPCs serially: we should
not send a new IPC command to the firmware before we get an ACK (or time
out) from firmware, and the IRQ processing is complete.
snd_pcm_period_elapsed() can be called in interrupt context before
IRQ_HANDLED is returned. When the PCM is done draining, a STOP
IPC will then be sent, which breaks the expectation that IPCs are
handled serially and leads to IPC timeouts.
This patch adds a workqueue to defer the call to snd_pcm_elapsed() after
the IRQ is handled.

By default, the I2S ports are configured in master mode during
DSP powerup sequences, the FS and BCLK lines will be driven on
startup, even when the topology file explicitly requires the
SSP to be slave.
This may be problematic for external components configured in
master mode who don't expect the Intel SOC/PCH to drive. Fix by
configuring the SSP as slave before the SSP outputs are enabled
to avoid this transient behavior.
When the topology file configures the SSP as clock master, the
initial slave configuration will be overridden.

When the kernel is more recent than firmware files, it will always
behave in backwards-compatible ways.
Add optional behavior to check if the kernel is older than the
firmware files, so that the kernel fails early instead of attempting
to use new functionality it does not support.

Currently in sst_dsp_new() if we get an error return from sst_dma_new()
we just print an error message and then still complete the function
successfully. This means that we are trying to run without sst->dma
properly set up, which will result in NULL pointer dereference when
sst->dma is later used. This was happening for me in
sst_dsp_dma_get_channel():
struct sst_dma *dma = dsp->dma;
...
dma->ch = dma_request_channel(mask, dma_chan_filter, dsp);
This resulted in:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000018
IP: sst_dsp_dma_get_channel+0x4f/0x125 [snd_soc_sst_firmware]
Fix this by adding proper error handling for the case where we fail to
set up DMA.
This change only affects Haswell and Broadwell systems. Baytrail
systems explicilty opt-out of DMA via sst->pdata->resindex_dma_base
being set to -1.
