Herve Codina <herve.codina@bootlin.com> says:
On some embedded system boards, audio amplifiers are designed using
discrete components such as op-amp, several resistors and switches to
either adjust the gain (switching resistors) or fully switch the
audio signal path (mute and/or bypass features).
Those switches are usually driven by simple GPIOs.
This kind of amplifiers are not handled in ASoC and the fallback is to
let the user-space handle those GPIOs out of the ALSA world.
In order to have those kind of amplifiers fully integrated in the audio
stack, this series introduces the audio-gpio-amp to handle them.
This new ASoC component allows to have the amplifiers seen as ASoC
auxiliarty devices and so it allows to control them through audio mixer
controls.
In order to ease the review, I choose to split modifications related
to the merge of the gpio-audio-amp part into the simple-amplfier driver
in several commits.

The possible gain values can be described using labels instead of gain
values in dB.
Those different labels are attached to a gpio values using the
gain-labels property.
Using the gain-labels description is mutually exclusive with gain-ranges
description used to describe the relationship between gpios values and
gain values.
Handle the gain-labels description and the related kcontrol.

The mapping between physical gain values and gpio values can be
expressed using ranges described in the gain-ranges property.
This gain-ranges property is an array of ranges.
Each range in the array is defined by the first point and last point in
the range. Those points are a pair of values, the gpios value and the
related gain (dB) value.
With that, a given range defines N possible items (from the first point
gpios value to the last point gpios value) in order to set a gain from
the first point gain value to the last point gain value.
Handle this description and the related kcontrol.

Improve the simple-amplifier introducing preliminary support for
gpio-audio-amp.
Those amplifiers are amplifiers driven by gpios.
This support introduction doesn't handle any GPIO yet but introduces
the compatible strings and the related DAPM table.
Two gpio-audio-amp are available: A mono and a stereo version.
The mono version has only one audio channel and gpio settings impact
features such as the gain or mute of this sole channel.
The stereo version has two channels (left and right). Gpio settings
impact both channels in the same manner and at the same time. For
instance, the gain setting set the gain of both channels as well as
the mute setting mutes both channels.

The simple-amplifier set the DAPM wigets and routes table in the ASoC
component driver. This is perfectly fine when the component has well
known DAPM tables.
The simple-amplifier is going to handle several kind of components based
on the driver compatible string. The DAPM table will not be the same for
all components supported by the driver.
In order to have different DAPM table based on matching compatible
strings, move those tables from the ASoC component driver to the device
compatible string matching data.
Add those DAPM widgets and routes dynamically during the ASoC component
probe operation.

The simple-amplifier driver use 'priv' as variable name for its private
data (struct simple_amp).
With the support for gpio-audio-amp, more functions and data
structures will be added.
Those future additions will add more complexity in data manipulation and
will make the 'priv' term error prone.
In order to clearly identify the struct simple_amp private data, use
'simple_amp' as variable name when this structure is involved.

The drv_event() is used to handle power events related to the DRV item.
Later, with the support for gpio-audio-amp, this function will be
also used to handle power events related to the PGA item.
Also, more functions will be added in the driver and it is a common
usage to prefix functions based on the driver name.
Rename the drv_event() function to simple_amp_power_event() to follow
common usage and get rid of the 'drv' term.

Some amplifiers based on analog switches and op-amps can be present in
the audio path and can be driven by GPIOs in order to control their gain
value, their mute and/or bypass functions.
Those components needs to be viewed as audio components in order to be
fully integrated in the audio path.
gpio-audio-amp allows to consider these GPIO driven amplifiers as
auxiliary audio devices.

The MT8196 AFE probe assigns reserved memory with
of_reserved_mem_device_init(), but never releases it.
This leaks the reserved memory assignment on driver
removal and on later probe failures.
The same probe path also uses unchecked pm_runtime_get_sync() calls.
A failure while resuming the device can leave the runtime PM usage
count in an unexpected state.
The regmap error path returns directly while the device is still
runtime active, and the remove path drops a runtime PM reference even
though successful probe has already released its temporary reference.
Register a devm cleanup action for the reserved memory assignment,
use pm_runtime_resume_and_get(), and only drop runtime PM references
on paths where they are actually held.

randconfig found more functions that are allowed for the remote code

- Fix remote_test error path
If one of the simple ring buffers fails to load, the code is supposed
to rollback its initialized buffers. Instead of rolling back the
buffers for the failed load, it uses the global variable and rolls
back all the successfully loaded buffers.

tracing: Fix desc in error path for the trace remote test module
ring-buffer remote: Avoid unexpected symbol warnings (arm, s390)
When issuing an extended guest request (SVM_VMGEXIT_EXT_GUEST_REQUEST),
get_ext_report() allocates a buffer to retrieve a certificate blob from the
host, keeping track of its size in report_req->certs_len.
However, the host may return SNP_GUEST_VMM_ERR_INVALID_LEN, indicating
an invalid buffer size, as well as the expected length of such buffer.
get_ext_report() subsequently updates report_req->certs_len with the
host-controlled value, and cleans up the buffer by computing a page order
from such value. This is incorrect, as the host-provided length may not
match the page order of the original allocation, potentially resulting
in corruption in the page allocator.
Fix this by using alloc_pages_exact() instead, and reusing @npages to
compute the size passed to free_pages_exact(). For consistency, also
use @npages to compute the size when allocating the pages, even though
this last change has no functional effect.

"Relatively low-impact fixes. Probably the most notable one is that we

This change avoids functional problems at some cost in performance,
but shouldn't affect any system with misaligned access handling in
hardware.

- Prevent the kernel from requesting delegation of misaligned access

Sashiko reports:
lm90_alert() executes in the smbus alert context and calls
lm90_update_confreg() to disable the hardware alert line, without
acquiring hwmon_lock.
Concurrently, sysfs write operations (such as lm90_write_convrate) hold
the hwmon_lock, temporarily modify data->config, and then restore it.
If an alert interrupt occurs concurrently with a sysfs write, the sysfs
path will overwrite the alert handler's modifications to data->config
and the hardware register.
This unintentionally re-enables the hardware alert line while the alarm is
still active, causing an interrupt storm.
Add the missing lock to lm90_alert() to solve the problem.

Sashiko reports:
In lm90_probe(), the devm action to cancel the alert_work and report_work
(lm90_restore_conf) is registered in lm90_init_client() before
devm_hwmon_device_register_with_info() is called.
Because devm executes cleanup actions in reverse order during module
unbind or probe failure, the hwmon device is unregistered and freed first.
If lm90_alert_work() or lm90_report_alarms() runs in the window between
the hwmon device being freed and the delayed works being cancelled,
lm90_update_alarms() will dereference the freed data->hwmon_dev here.
Fix the problem by canceling the workers separately after registering
the hwmon device and before registering the interrupt handler. This ensures
that the workers are canceled after interrupts are disabled and before
the hwmon device is released. Add "shutdown" flag to indicate that device
shutdown is in progress to prevent workers from being re-armed.

- in tracepoint of file sync, fix sleeping in atomic context when
handling dentries
- harden initial loading of block group on crafted/fuzzed images,
iterate all chunk mapping entries unconditionally
- fix freeing pages of submitted io after checking for errors
- fix incorrect inode size after remount when using fallocate KEEP_SIZE
mode (also requires disabled 'no-holes' feature)
