TC Applied Technologies (TCAT) have added extension to DICE protocol. This
protocol extension is called as Extended Application Protocol, a.k.a. EAP.
In this protocol extension, units get additional 9 address spaces. One of
it is for current configuration. In this address space, a pair of router
and stream formats are exposed per mode of three sampling transmission
frequencies.
This commit adds support the protocol extension for address space of the
current configuration to generate cache of stream formats.

Alesis shipped some models with DICE ASICs. All of them just support
DICE original protocol and drivers can't retrieve all of available stream
formats without changing status of sampling transmission frequency
actually.
This commit puts some hard-coded parameters for the models. When detecting
the models, the corresponding parameters are copied as cache of stream
formats.
I note that each of pair of iO14/iO26 and MultiMix 8/12/16 has the same
model ID on their configuration ROM. The MultiMix 8/12/16 just support
one mode for sampling transmission frequency and ALSA dice driver already
handles them correctly. The iO14/iO26 support three modes and need
hard-coded parameters. To distinguish these two models, this commit let
the driver to retrieve current stream formats and compare it to known
parameters, then decide it.

Products with DICE interface in market can support variable stream

Unlike the other drivers in ALSA firewire stack, ALSA dice driver does't
create 'firewire' directory for proc nodes because it has 'dice' node
only. But this is inconvenient because I have a plan to add another proc
node to output available stream formats from cache.
This commit let the driver to create the directory and put 'dice' node
into it.

A previous commit 6f688268b3f4 ('ALSA: dice: purge generating channel
cache') purged cache of stream formats. DICE interface originally has
no feature to assist drivers to retrieve available formats for all of
supported sampling transmission frequencies, without changing the
frequency actually.
For later release of Dice ASICs such as TCD2210, Dice interface has
extended protocol and can support the feature. This assists drivers
to retrieve available stream formats.
This commit is a first step to regain the cache to generate PCM rules
for all of supported sampling transmission frequencies.

DECLARE_TLV_DB_SCALE (alias of SNDRV_CTL_TLVD_DECLARE_DB_SCALE) is used but
tlv.h is not included. This causes build failure when local macro is
defined by comment-out.
This commit fixes the bug. At the same time, the alias macro is replaced
with a destination macro added at a commit 46e860f76804 ("ALSA: rename

The DP-MST support requires more PCM streams than usual, hence
CONFIG_SND_DYNAMIC_MINORS is almost mandatory. Currently the driver
just warns and continues even if streams are missing, but it doesn't
seem to enough convince users to switch to the modern setup.
This patch adds the enforced selection of CONFIG_SND_DYNAMIC_MINORS
from CONFIG_SND_HDA_CODEC_HDMI for covering that.

Since snd_pcm_ioctl_xfern_compat() has no PCM state check, it may go
further and hit the sanity check pcm_sanity_check() when the ioctl is
called right after open. It may eventually spew a kernel warning, as
triggered by syzbot, depending on kconfig.
The lack of PCM state check there was just an oversight. Although
it's no real crash, the spurious kernel warning is annoying, so let's
add the proper check.

According to "EP93xx User’s Guide", I2STXLinCtrlData and I2SRXLinCtrlData
registers actually have different format. The only currently used bit
(Left_Right_Justify) has different position. Fix this and simplify the
whole setup taking into account the fact that both registers have zero
default value.
The practical effect of the above is repaired SND_SOC_DAIFMT_RIGHT_J
support (currently unused).

for array index
At a commit f91c9d7610a ('ALSA: firewire-lib: cache maximum length of
payload to reduce function calls'), maximum size of payload for tx
isochronous packet is cached to reduce the number of function calls.
This cache was programmed to updated at a first callback of ohci1394 IR
context. However, the maximum size is required to queueing packets before
starting the isochronous context.
As a result, the cached value is reused to queue packets in next time to
starting the isochronous context. Then the cache is updated in a first
callback of the isochronous context. This can cause kernel NULL pointer
dereference in a below call graph:
(sound/firewire/amdtp-stream.c)
amdtp_stream_start()
->queue_in_packet()
->queue_packet()
(drivers/firewire/core-iso.c)
->fw_iso_context_queue()
->struct fw_card_driver.queue_iso()
(drivers/firewire/ohci.c)
= ohci_queue_iso()
->queue_iso_packet_per_buffer()
buffer->pages[page]
The issued dereference occurs in a case that:
- target unit supports different stream formats for sampling transmission
frequency.
- maximum length of payload for tx stream in a first trial is bigger
than the length in a second trial.
In this case, correct number of pages are allocated for DMA and the 'pages'
array has enough elements, while index of the element is wrongly calculated
according to the old value of length of payload in a call of
'queue_in_packet()'. Then it causes the issue.
This commit fixes the critical bug. This affects all of drivers in ALSA
firewire stack in Linux kernel v4.12 or later.

The sequencer virmidi code has an open race at its output trigger
callback: namely, virmidi keeps only one event packet for processing
while it doesn't protect for concurrent output trigger calls.
snd_virmidi_output_trigger() tries to process the previously
unfinished event before starting encoding the given MIDI stream, but
this is done without any lock. Meanwhile, if another rawmidi stream
starts the output trigger, this proceeds further, and overwrites the
event package that is being processed in another thread. This
eventually corrupts and may lead to the invalid memory access if the
event type is like SYSEX.
The fix is just to move the spinlock to cover both the pending event
and the new stream.
The bug was spotted by a new fuzzer, RaceFuzzer.

sound/soc/fsl/fsl_ssi.c:398:42: got restricted __be32 [addressable] [usertype] sisr
In other places where regmap_read() is used a u32 variable is passed
to store the register read value, so do the same here as well.
regmap API already takes care of endianness, so the usage of u32 is safe.

This patch adds support for the MT7622 AFE which reuses MT2701 driver.
We also introduce the 'struct mt2701_soc_variants' to differentiate
between the SoC generations as there might be other (existing or future)
chips that use the same binding and driver, then being a little more
abstract could help in the long run.

There are 2 loops calling open and 4 loops calling free for all the
components on a DAI link. Factor out these loops into helper functions
to make the code a little clearer.

The core should only call free on a component if said component has
already had open called on it. This is not presently the case and most
compressed drivers in the kernel assume it will be. This causes null
pointer dereferences in the drivers as they attempt clean up for stuff
that was never put in place.
This is fixed by aborting calling open callbacks once a failure is
encountered and then during clean up only iterating through the
component list to that point.
This is a fairly quick fix to the issue, to allow backporting. There
is more refactoring to follow to tidy the code up a little.
