ASoC: Fixes for v6.18
A moderately large collection of driver specific fixes, plus a few new
quirks and device IDs. The NAU8821 changes are a little large but more
in mechanical ways than in ways that are complex.
Merge series from Cristian Ciocaltea <cristian.ciocaltea@collabora.com>:
This patch series addresses a set of issues in the Nuvoton NAU88L21
audio codec driver related to interrupt handling and jack hotplug
detection reliability.
The changes focus on:
* Eliminating race conditions between jack insertion and ejection events
* Ensuring interrupts are consistently and correctly cleared before
unmasking
* Introducing a DMI-based quirk to bypass the jack debounce circuit on
Valve Steam Deck, improving detection accuracy under stress
* Improving robustness of the IRQ handler by avoiding unnecessary
blocking operations
The series has been tested on affected hardware to verify correct
behavior during repeated and rapid jack hotplug cycles.
Merge series from Le Qi <le.qi@oss.qualcomm.com>:
This patch series adds support for the QCS615 sound card:
- Updates device tree bindings for SM8250 to include QCS615.
- Adds QCS615 support in the SC8280XP ASoC driver.

The interrupt handler offloads the microphone detection logic to
nau8821_jdet_work(), which implies a sleep operation. However, before
being able to process any subsequent hotplug event, the interrupt
handler needs to wait for any prior scheduled work to complete.
Move the sleep out of jdet_work by converting it to a delayed work.
This eliminates the undesired blocking in the interrupt handler when
attempting to cancel a recently scheduled work item and should help
reducing transient input reports that might confuse user-space.

Stress testing the audio jack hotplug handling on a few Steam Deck units
revealed that the debounce circuit is responsible for having a negative
impact on the detection reliability, e.g. in some cases the ejection
interrupt is not fired, while in other instances it goes into a kind of
invalid state and generates a flood of misleading interrupts.
Add new entries to the DMI table introduced via commit 1bc40efdaf
("ASoC: nau8821: Add DMI quirk mechanism for active-high jack-detect")
and extend the quirk logic to allow bypassing the debounce circuit used
for jack detection on Valve Steam Deck LCD and OLED models.
While at it, rename existing NAU8821_JD_ACTIVE_HIGH quirk bitfield to
NAU8821_QUIRK_JD_ACTIVE_HIGH. This should help improve code readability
by differentiating from similarly named register bits.

The interrupt handler attempts to perform some IRQ status clear
operations *after* rather than *before* unmasking and enabling
interrupts. This is a rather fragile approach since it may generally
lead to missing IRQ requests or causing spurious interrupts.
Make use of the nau8821_irq_status_clear() helper instead of
manipulating the related register directly and ensure any interrupt
clearing is performed *after* the target interrupts are disabled/masked
and *before* proceeding with additional interrupt unmasking/enablement
operations.
This also implicitly drops the redundant clear operation of the ejection
IRQ in the interrupt handler, since nau8821_eject_jack() has been
already responsible for clearing all active interrupts.

Instead of adding yet another utility function for dealing with the
interrupt clearing register, generalize nau8821_int_status_clear_all()
by renaming it to nau8821_irq_status_clear(), whilst introducing a
second parameter to allow restricting the operation scope to a single
interrupt instead of the whole range of active IRQs.
While at it, also fix a spelling typo in the comment block.
Note this is mainly a prerequisite for subsequent patches aiming to
address some deficiencies in the implementation of the interrupt
handler. Thus the presence of the Fixes tag below is intentional, to
facilitate backporting.

The microphone detection work scheduled by a prior jack insertion
interrupt may still be in a pending state or under execution when a jack
ejection interrupt has been fired.
This might lead to a racing condition or nau8821_jdet_work() completing
after nau8821_eject_jack(), which will override the currently
disconnected state of the jack and incorrectly report the headphone or
the headset as being connected.
Cancel any pending jdet_work or wait for its execution to finish before
attempting to handle the ejection interrupt.
Proceed similarly before launching the eject handler as a consequence of
detecting an invalid insert interrupt.

The previous fix to trace_marker required updating trace_marker_raw
as well. The difference between trace_marker_raw from trace_marker
is that the raw version is for applications to write binary structures
directly into the ring buffer instead of writing ASCII strings.
This is for applications that will read the raw data from the ring
buffer and get the data structures directly. It's a bit quicker than
using the ASCII version.
Unfortunately, it appears that our test suite has several tests that
test writes to the trace_marker file, but lacks any tests to the
trace_marker_raw file (this needs to be remedied). Two issues came
about the update to the trace_marker_raw file that syzbot found:
- Fix tracing_mark_raw_write() to use per CPU buffer
The fix to use the per CPU buffer to copy from user space was needed for
both the trace_maker and trace_maker_raw file.
The fix for reading from user space into per CPU buffers properly fixed
the trace_marker write function, but the trace_marker_raw file wasn't
fixed properly. The user space data was correctly written into the per CPU
buffer, but the code that wrote into the ring buffer still used the user
space pointer and not the per CPU buffer that had the user space data
already written.
- Stop the fortify string warning from writing into trace_marker_raw
After converting the copy_from_user_nofault() into a memcpy(), another
issue appeared. As writes to the trace_marker_raw expects binary data, the
first entry is a 4 byte identifier. The entry structure is defined as:
struct {
struct trace_entry ent;
int id;
char buf[];
};
The size of this structure is reserved on the ring buffer with:
size = sizeof(*entry) + cnt;
Then it is copied from the buffer into the ring buffer with:
memcpy(&entry->id, buf, cnt);
This use to be a copy_from_user_nofault(), but now converting it to
a memcpy() triggers the fortify-string code, and causes a warning.
The allocated space is actually more than what is copied, as the cnt
used also includes the entry->id portion. Allocating sizeof(*entry)
plus cnt is actually allocating 4 bytes more than what is needed.
Change the size function to:
size = struct_size(entry, buf, cnt - sizeof(entry->id));
And update the memcpy() to unsafe_memcpy().

Fixes only in drivers (ufs, mvsas, qla2xxx, target) that came in just
before or during the merge window. The most important one is the
qla2xxx which reverts a conversion to fix flexible array member
warnings, that went up in this merge window but which turned out on
further testing to be causing data corruption.

There're several different actual hardwares sold by Huawei, using the
same USB ID 12d1:3a07.
The first one we found, having a volume control named "Headset Playback
Volume", reports a min value -15360, and will mute iff setting it to
-15360. It can be simply fixed by quirk flag MIXER_PLAYBACK_MIN_MUTE,
which we have already submitted previously.[1]
The second one we found today, having a volume control named "PCM
Playback Volume", reports its min -11520 and res 256, and will mute
when less than -11008. Because of the already existing quirk flag, we
can just set its min to -11264, and the new minimum value will still
not be available to userspace, so that userspace's minimum will be the
correct -11008.

The __component_match_add function may assign the 'matchptr' pointer
the value ERR_PTR(-ENOMEM), which will subsequently be dereferenced.
The call stack leading to the error looks like this:
hda_component_manager_init
|-> component_match_add
|-> component_match_add_release
|-> __component_match_add ( ... ,**matchptr, ... )
|-> *matchptr = ERR_PTR(-ENOMEM); // assign
|-> component_master_add_with_match( ... match)
|-> component_match_realloc(match, match->num); // dereference
Add IS_ERR() check to prevent the crash.

Return value of a function acpi_evaluate_dsm() is dereferenced without
checking for NULL, but it is usually checked for this function.
acpi_evaluate_dsm() may return NULL, when acpi_evaluate_object() returns
acpi_status other than ACPI_SUCCESS, so add a check to prevent the crach.

The fix to use a per CPU buffer to read user space tested only the writes
to trace_marker. But it appears that the selftests are missing tests to
the trace_maker_raw file. The trace_maker_raw file is used by applications
that writes data structures and not strings into the file, and the tools
read the raw ring buffer to process the structures it writes.
The fix that reads the per CPU buffers passes the new per CPU buffer to
the trace_marker file writes, but the update to the trace_marker_raw write
read the data from user space into the per CPU buffer, but then still used
then passed the user space address to the function that records the data.
Pass in the per CPU buffer and not the user space address.
