ALSA: seq: Serialize UMP output teardown with event_input
seq_ump_process_event() borrows client->out_rfile.output without
synchronizing with the first-open and last-close transition in
seq_ump_client_open() and seq_ump_client_close().
The last output unuse can therefore drop opened[STR_OUT] to zero and
release the rawmidi file while an in-flight event_input callback is still
inside snd_rawmidi_kernel_write(). That leaves the rawmidi substream
runtime exposed to teardown before the write path has taken its own
buffer reference.
Add a per-client rwlock for the event_input-visible output file. Publish
a newly opened output file under the write side, and hold the read side
from the output lookup through snd_rawmidi_kernel_write(). The last
output close copies and clears the visible output file under the write
side, then drops the lock and releases the saved rawmidi file. Use
IRQ-safe rwlock guards because event_input can also be reached from
atomic sequencer delivery.
The buggy scenario involves two paths, with each column showing the
order within that path:
path A label: event_input path path B label: last unuse path
1. seq_ump_process_event() reads 1. seq_ump_client_close()
client->out_rfile.output. drops opened[STR_OUT] to zero.
2. snd_rawmidi_kernel_write1() 2. snd_rawmidi_kernel_release()
has not yet pinned runtime. closes the output file.
3. The writer continues using 3. close_substream() frees
the borrowed substream. substream->runtime.
This keeps the output substream and runtime alive for the full
event_input write while keeping rawmidi release outside the rwlock.
KASAN reproduced this as a slab-use-after-free in
snd_rawmidi_kernel_write1(), with allocation through
seq_ump_use()/snd_seq_port_connect() and free through
seq_ump_unuse()/snd_seq_port_disconnect().

ASoC: fsl_sai: Eliminate possible interrupt storm during probe
When the SAI peripheral is left in a running state by the bootloader,
the driver can experience an interrupt storm during probe that prevents
successful initialization. This occurs because the current code registers
the IRQ handler before resetting the hardware to a known state.
The issue manifests as:
- Continuous interrupts firing immediately after devm_request_irq()
- Driver probe failure or system hang
- Error messages about unhandled interrupts
This is particularly problematic on systems where U-Boot or other
bootloaders enable SAI for boot-time audio feedback or diagnostics
and don't properly disable it before handing control to Linux.
Fix this by reordering the probe sequence:
1. Add fsl_sai_reset_hw() to clear TCSR/RCSR control registers,
which disables the transmitter/receiver and all interrupt sources
2. Move devm_request_irq() to after hardware initialization
This ensures the SAI is in a clean reset state before the interrupt
handler can be invoked, preventing the storm while maintaining proper
error handling and cleanup paths.

hwmon: (lm90) Add lock protection to lm90_alert
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.

hwmon: (lm90) Stop work before releasing hwmon device
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.

[lkml.kernel.org/lkml/2025/6/13/1380]) for the generic snd_parse_eld()
helper used by ASoC hdmi-codec.
When a HDMI sink is disconnected (e.g. a board with two HDMI outputs and
only one cable), userspace audio servers like PipeWire keep probing the
disconnected card and trigger:
HDMI: Unknown ELD version 0
at every probe — easily 30+ messages per burst on rk3588. The same
applies to malformed ELD (MNL out of range). Both conditions are
expected when no sink is attached; rate-limit the dev_info() so the
kernel ring buffer does not fill up.

The ASUS Zenbook S16 (UM5606GA) with AMD Ryzen AI 9 465 (Strix Point,
ACP 7.0) has a BIOS that incorrectly sets the ACPI property
'acp-audio-config-flag' to 0x10 (FLAG_AMD_LEGACY_ONLY_DMIC) for the ACP

in no internal audio (dummy output only).
The hardware uses a Cirrus Logic CS42L43 (headphone/jack) and four CS35L56
smart amplifiers (speakers), all on SoundWire link 1. The corresponding
machine table entry (acp70_cs42l43_l1u0_cs35l56x4_l1u0123) already exists
in amd-acp70-acpi-match.c and correctly describes this topology.

ASoC: amd: acp-sdw-legacy: check CPU DAI name before logging
devm_kasprintf() can fail and return NULL. The legacy AMD SoundWire
machine driver logs cpus->dai_name before checking the allocation result.
Move the debug print after the NULL check, matching the ordering used by
the SOF AMD SoundWire path after commit 5726b68473f7 ("ASoC: amd/sdw_utils:
avoid NULL deref when devm_kasprintf() fails").
ASoC: qcom: q6apm-dai: Allocate an extra page for PCM buffers
Some Old DSP firmware versions use 32-bit address arithmetic and size for
validating the PCM buffer address range. If a buffer is allocated near
the top of the 32-bit address space, arithmetic calculations involving
the end address can overflow and fail checks.
Work around this by increasing the preallocated PCM buffer size by one
page. The DSP is still passed the usable buffer size, excluding the extra
page, which prevents the firmware from seeing an end address that crosses
the 32-bit boundary.
This was not hit before because PCM buffer allocation and DSP-side
mapping happened at different points, and the size mapped on the DSP was
usually nperiods * period_size. Therefore the mapped size was unlikely to
match the full preallocated buffer size exactly, although the issue was
still possible. With early buffer mapping on the DSP, the full
preallocated buffer is mapped during PCM creation, making the failure
reproducible at boot.

ALSA: hda/ca0132: Disable auto-detect on manual output select
Commit 778031e1658d ("ALSA: hda/ca0132: Set HP/Speaker
auto-detect default from headphone pin verb") enables HP/Speaker
auto-detect by default when the headphone pin supports presence detect.
With auto-detect enabled, ca0132_select_out() and ca0132_alt_select_out()
choose the output from jack presence instead of the manual HP/Speaker
selection. This means selecting speaker output while headphones are
plugged in updates the control state, but audio still routes to the
headphones.
Treat an explicit manual output selection as a request to leave
auto-detect mode. Clear the HP/Speaker auto-detect switch before applying
the manual selection, and notify userspace so the auto-detect control
state is updated in mixers. Do this for both the normal HP/Speaker
Playback Switch and the alternate Output Select control used by desktop
cards.
This keeps auto-detect enabled by default for devices with jack presence
detection, while preserving the expected behavior that a manual output
choice takes effect immediately.

the failed mapping also leaves the IOVA allocator state marked in use.

construction fails, free the sg table when transfer-buffer IOMMU mapping

iommupt: Fix the end_index calculation in __map_range_leaf()
Sashiko noticed a mismatch of units in this math: num_leaves is
actually the number of leaf *entries* (so a 16-item contiguous leaf

causes __map_range_leaf() to exit early instead of efficiently
filling a larger range of contiguous PTEs.
The early exit is caught by the functions above and then
__map_range_leaf() is re-invoked, so there is no functional issue.

size and avoid the performance cost of looping externally.

- Promote the illegal domain->type to a WARN_ON

- 0 pgsize_bitmap WARN_ON
- Promote the illegal domain->type to a WARN_ON
