[ Upstream commit b1f373a11d25fc9a5f7679c9b85799fe09b0dc4a ]
VAG power control is improved to fit the manual [1]. This patch fixes as
minimum one bug: if customer muxes Headphone to Line-In right after boot,
the VAG power remains off that leads to poor sound quality from line-in.
I.e. after boot:
- Connect sound source to Line-In jack;
- Connect headphone to HP jack;
- Run following commands:
$ amixer set 'Headphone' 80%
$ amixer set 'Headphone Mux' LINE_IN
Change VAG power on/off control according to the following algorithm:
- turn VAG power ON on the 1st incoming event.
- keep it ON if there is any active VAG consumer (ADC/DAC/HP/Line-In).
- turn VAG power OFF when there is the latest consumer's pre-down event
come.
- always delay after VAG power OFF to avoid pop.
- delay after VAG power ON if the initiative consumer is Line-In, this
prevents pop during line-in muxing.
According to the data sheet [1], to avoid any pops/clicks,
the outputs should be muted during input/output
routing changes.

commit e1a00b5b253a4f97216b9a33199a863987075162 upstream.
2 bytes in MSB of register for clock status is zero during intermediate
state after changing status of sampling clock in models of TASCAM FireWire
series. The duration of this state differs depending on cases. During the
state, it's better to retry reading the register for current status of
the clock.
In current implementation, the intermediate state is checked only when
getting current sampling transmission frequency, then retry reading.
This care is required for the other operations to read the register.
This commit moves the codes of check and retry into helper function
commonly used for operations to read the register.

setups to override the EAPD via COEF or BTL in the additional verb

this EAPD setup is again overridden in alc_auto_init_amp().
For recovering from the regression, tell snd_hda_gen_init() not to
apply the verbs there by a new flag, then apply the verbs in

Applying slot_width constraint to sample_bits works most of the time, but
it will blacklist valid formats in some cases.
With slot_width 24 we can support S24_3LE and S24_LE formats as they both
look the same on the bus, but a a 24 constraint on sample_bits would not
allow S24_LE as it is stored in 32bits in memory.
Implement a simple hw_rule function to allow all formats which require less

A previous fix to the stop handling on compressed capture streams causes
some knock on issues. The previous fix updated snd_compr_drain_notify to
set the state back to PREPARED for capture streams. This causes some
issues however as the handling for snd_compr_poll differs between the
two states and some user-space applications were relying on the poll
failing after the stream had been stopped.
To correct this regression whilst still fixing the original problem the
patch was addressing, update the capture handling to skip the PREPARED
state rather than skipping the SETUP state as it has done until now.

commit ede34f397ddb063b145b9e7d79c6026f819ded13 upstream.
The fix for the racy writes and ioctls to sequencer widened the
application of client->ioctl_mutex to the whole write loop. Although
it does unlock/relock for the lengthy operation like the event dup,
the loop keeps the ioctl_mutex for the whole time in other
situations. This may take quite long time if the user-space would
give a huge buffer, and this is a likely cause of some weird behavior
spotted by syzcaller fuzzer.
This patch puts a simple workaround, just adding a mutex break in the
loop when a large number of events have been processed. This
shouldn't hit any performance drop because the threshold is set high
enough for usual operations.

commit 7fbd1753b64eafe21cf842348a40a691d0dee440 upstream.
In IEC 61883-6, 8 MIDI data streams are multiplexed into single
MIDI conformant data channel. The index of stream is calculated by
modulo 8 of the value of data block counter.
In fireworks, the value of data block counter in CIP header has a quirk
with firmware version v5.0.0, v5.7.3 and v5.8.0. This brings ALSA
IEC 61883-1/6 packet streaming engine to miss detection of MIDI
messages.
This commit fixes the miss detection to modify the value of data block
counter for the modulo calculation.
For maintainers, this bug exists since a commit 18f5ed365d ("ALSA:
fireworks/firewire-lib: add support for recent firmware quirk") in Linux
kernel v4.2. There're many changes since the commit. This fix can be
backported to Linux kernel v4.4 or later. I tagged a base commit to the
backport for your convenience.
Besides, my work for Linux kernel v5.3 brings heavy code refactoring and
some structure members are renamed in 'sound/firewire/amdtp-stream.h'.
The content of this patch brings conflict when merging -rc tree with
this patch and the latest tree. I request maintainers to solve the
conflict to replace 'tx_first_dbc' with 'ctx_data.tx.first_dbc'.

commit 7c32ae35fbf9cffb7aa3736f44dec10c944ca18e upstream.
The call of unsubscribe_port() which manages the group count and
module refcount from delete_and_unsubscribe_port() looks racy; it's
not covered by the group list lock, and it's likely a cause of the
reported unbalance at port deletion. Let's move the call inside the
group list_mutex to plug the hole.

[ Upstream commit f495222e28275222ab6fd93813bd3d462e16d340 ]
Currently the IRQ handler in HD-audio controller driver is registered
before the chip initialization. That is, we have some window opened
between the azx_acquire_irq() call and the CORB/RIRB setup. If an
interrupt is triggered in this small window, the IRQ handler may
access to the uninitialized RIRB buffer, which leads to a NULL
dereference Oops.
This is usually no big problem since most of Intel chips do register
the IRQ via MSI, and we've already fixed the order of the IRQ
enablement and the CORB/RIRB setup in the former commit b61749a89f82
("sound: enable interrupt after dma buffer initialization"), hence the
IRQ won't be triggered in that room. However, some platforms use a
shared IRQ, and this may allow the IRQ trigger by another source.
Another possibility is the kdump environment: a stale interrupt might
be present in there, the IRQ handler can be falsely triggered as well.
For covering this small race, let's move the azx_acquire_irq() call
after hda_intel_init_chip() call. Although this is a bit radical
change, it can cover more widely than checking the CORB/RIRB setup
locally in the callee side.

commit 317d9313925cd8388304286c0d3c8dda7f060a2d upstream.
I measured power consumption between power_save_node=1 and power_save_node=0.
It's almost the same.
Codec will enter to runtime suspend and suspend.
That pin also will enter to D3. Don't need to enter to D3 by single pin.
So, Disable power_save_node as default. It will avoid more issues.
Windows Driver also has not this option at runtime PM.

is_slave_mode defaults to false because sai structure

Anyhow, if we decide to set the following configuration
SAI slave -> SAI master, is_slave_mode will remain set on true

imx-ssi.c:(.text+0xa64): undefined reference to `imx_pcm_fiq_init'
The Kconfig warning is a result of the symbol being defined inside of
the "if SND_IMX_SOC" block, and is otherwise harmless. The link error
is more tricky and happens with SND_SOC_IMX_SSI=y, which may or may not
imply FIQ support. However, if SND_SOC_FSL_SSI is set to =m at the same
time, that selects SND_SOC_IMX_PCM_FIQ as a loadable module dependency,
which then causes a link failure from imx-ssi.
The solution here is to make SND_SOC_IMX_PCM_FIQ built-in whenever
one of its potential users is built-in.

commit a46eb523220e242affb9a6bc9bb8efc05f4f7459 upstream.
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.

commit ecb2795c08bc825ebd604997e5be440b060c5b18 upstream.
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.

commit 7f641e26a6df9269cb25dd7a4b0a91d6586ed441 upstream.
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.

commit cb5173594d50c72b7bfa14113dfc5084b4d2f726 upstream.
In parse_audio_selector_unit(), the string array 'namelist' is allocated
through kmalloc_array(), and each string pointer in this array, i.e.,
'namelist[]', is allocated through kmalloc() in the following for loop.
Then, a control instance 'kctl' is created by invoking snd_ctl_new1(). If
an error occurs during the creation process, the string array 'namelist',
including all string pointers in the array 'namelist[]', should be freed,
before the error code ENOMEM is returned. However, the current code does
not free 'namelist[]', resulting in memory leaks.
To fix the above issue, free all string pointers 'namelist[]' in a loop.

commit 0efa3334d65b7f421ba12382dfa58f6ff5bf83c4 upstream.
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.
