Override input device open() and close() callbacks to enable and disable
the force-feedback workqueue item synchronously.
When the input device is opened by userspace, call hid_hw_open() and
enable_work(). When it is closed, disable_work_sync() ensures that any
pending or running work item is cancelled/flushed and no further work
items can be scheduled.
In close(), zero out magnitudes and issue a final report to turn off the
rumble motors on the physical controller before shutting down transport
I/O.
Pack strong and weak magnitudes into a single u32 integer using
WRITE_ONCE() and READ_ONCE() for atomic, lockless updates.
This allows eliminating the manual 'removed' boolean flag and spinlock
completely.

HID drivers that rely on the HID core to register input devices must
ensure that all private data and capabilities (like force-feedback) are
fully initialized before registration.
When hid_hw_start() is called with HID_CONNECT_HIDINPUT, the input
device is registered immediately. This is racy if the driver attempts to
augment the input device in probe() after starting the hardware.
The correct way to handle this is to use the .input_configured()
callback.
Add documentation and a Coccinelle script to detect and prevent this
anti-pattern.

Some HID drivers initialize their own force-feedback support within
their .input_configured() callback. In such cases, we should skip
the generic PID force-feedback initialization to avoid conflicts and
redundant setup.
Add hid_has_ff_input() helper and use it to check for existing FF
capabilities before calling hdev->ff_init().
Since we now have a dynamic way to detect if force-feedback is needed,
the HID_CONNECT_FF flag is redundant for conflict resolution and can
be ignored in the core initialization logic. Generic PID support will
now be attempted by default for any claimed input device that doesn't
already have FF capabilities.

The SFH accessors reach the device through a file-global emp2 pointer
that is published at probe and cleared on remove. amd_get_sfh_info() is
exported and called from other modules on unrelated threads, so a reader
can observe a non-NULL emp2 and then race a concurrent unbind that clears
it and frees the device.
Serialize the emp2 publish/clear and all readers under a mutex, so a
reader either sees a live device for the whole access or sees NULL.

The MP2 version is currently known only implicitly, from whether an ops

act on the MP2 version directly, for example to read the operating-mode

The controller has DTR support, a bit must be set for it. The behaviour
is interesting though, as the speed won't improve when enabled. This is
because there seems to be an internal divisor (/2) which keeps the rate
equal when DTR is enabled. As a result, this commit also doubles the
target bus speed, which in practice does not happen. This way, there is
a real gain:
Before:
$ flash_speed /dev/mtd0 -dc10
eraseblock write speed is 1000 KiB/s
[...]
eraseblock read speed is 1199 KiB/s

After:
$ flash_speed /dev/mtd0 -dc10

The speed setting is wrongly placed inside the "setup transfer" helper,
since the bus configuration may require the speed to be correct. Indeed,
DTR mode (not yet available) divides by 2 the bus clock when enabled. As
a result, to remain at a constant clock speed (and improve the data
rate), we must double the bus clock when enabling DTR. In order to
prepare for this change, move all the bus configuration required for
each step of the operation inside a unique helper called
nuvoton_qspi_configure_bus().

For GHL (Guitar Hero Live) dongles, sony_probe() arms a periodic timer:
ghl_magic_poke() (the timer callback) submits sc->ghl_urb, and the URB
completion ghl_magic_poke_cb() re-arms the timer with mod_timer().
sony_remove() drained the timer with timer_delete_sync() and then freed
the URB with usb_free_urb():
timer_delete_sync(&sc->ghl_poke_timer);
usb_free_urb(sc->ghl_urb);
timer_delete_sync() does not block re-arming, and while the URB is in
flight the timer is not pending, so the sync delete is a no-op. A URB
completion that runs after the delete re-arms the timer, and usb_free_urb()
only drops a reference -- it does not kill an in-flight URB. sc is
allocated with devm_kzalloc() and freed once sony_remove() returns, so the
re-armed ghl_poke_timer (embedded in sc) then fires on freed memory, a
use-after-free from timer softirq. This is a disconnect/rmmod race.
Poison the URB first, then shut the timer down, before freeing the URB.
usb_poison_urb() kills any in-flight URB and permanently rejects further
submissions, so a poke timer that is still pending cannot re-submit the
URB from ghl_magic_poke() in the window before timer_shutdown_sync() runs.
usb_kill_urb() would not suffice: it only cancels the in-flight URB and
leaves it submittable once it returns, so the pending timer could
re-submit it and put a fresh URB in flight over the freed sc.
timer_shutdown_sync() then drains any last callback and blocks re-arming.
The probe error path is unaffected: it is only reached before the timer
is armed.
Reproduced under KASAN on next-20260710 via dummy_hcd + raw-gadget
emulation of the GHL PS4 dongle (VID 0x1430 / PID 0x07bb): hid-sony binds
and arms the poke timer, the poke URB is held in flight, the driver is
unbound (freeing sc), then the URB is released. The completion re-arms the
timer on the freed sc, and the re-armed timer fires ~8 s later:

A use-after-free was detected in snd_card_do_free() when a sound card
managed by devres is unbound while a user-space application still holds an
open file descriptor.
For managed cards, the memory is allocated using devres_alloc(), and its
release function is set to __snd_card_release(), which calls
snd_card_free(). When the device is unbound, the unbind thread calls
snd_card_free(), which drops a reference to the card's device. If the user
thread still has an open file descriptor, the reference count does not
reach zero, and the unbind thread blocks on wait_for_completion(&released).
When the user thread closes the file descriptor, it drops the final
reference, invoking the device release callback release_card_device(),
which calls snd_card_do_free(). snd_card_do_free() performs cleanup and
calls complete(card->release_completion). This wakes up the unbind thread,
which returns from snd_card_free() and __snd_card_release(). The devres
core then immediately frees the memory block containing the snd_card
structure.
Meanwhile, the user thread continues execution in snd_card_do_free() and
evaluates `if (!card->managed)`. It reads the `managed` boolean from the
snd_card structure that was just freed by the unbind thread, triggering a
KASAN use-after-free.
Fix this by caching the value of card->managed in a local variable before
calling complete(). This ensures that the card pointer is not dereferenced
after the unbind thread has been woken up and potentially freed the card.

sock_is_scoped() dereferences other->sk_socket->file->f_cred to read the
peer's Landlock domain when evaluating
LANDLOCK_SCOPE_ABSTRACT_UNIX_SOCKET, without first checking that the
peer has a backing socket and file. hook_unix_find() performs the same
dereference for LANDLOCK_ACCESS_FS_RESOLVE_UNIX and does guard it.
Guard it here too and treat a peer with no backing file, such as a
kernel socket created by sock_create_kern(), as unscoped.
This is defensive hardening, not a fix for a reachable bug. The
unix_stream_connect() and unix_may_send() hooks run with the peer held
under unix_state_lock() and only after the AF_UNIX core has excluded
SOCK_DEAD, and no in-tree code binds a file-less AF_UNIX socket to an
abstract address, so other->sk_socket->file is always valid at these
call sites today.

The PCI SSID 17aa:38df is listed twice in alc269_fixup_tbl[], both mapping
to the same fixup ALC287_FIXUP_TAS2781_I2C:
SND_PCI_QUIRK(0x17aa, 0x38df, "Yoga Y990 Intel YC Dual", ALC287_FIXUP_TAS2781_I2C),
...
SND_PCI_QUIRK(0x17aa, 0x38df, "Y990 YG DUAL", ALC287_FIXUP_TAS2781_I2C),
The HDA quirk lookup (hda_quirk_lookup_id()) returns the first matching
entry, so the second occurrence never takes effect; it is dead code.
Drop the second entry. The retained "Yoga Y990 Intel YC Dual" label also
follows the naming of the neighbouring 0x38e0 entry ("Yoga Y990 Intel VECO
Dual").

Set the drive strength before enabling the output to avoid enabling
the output with an unintended drive strength.
Also return the actual output enable state from
PIN_CONFIG_OUTPUT_ENABLE instead of always reporting it as enabled.

Add support for PIN_CONFIG_INPUT_ENABLE in the Amlogic A4 pinctrl
driver.
Use the existing output enable control to configure the input enable
state, since the hardware uses the same control with inverse semantics.
Also update PIN_CONFIG_OUTPUT_ENABLE handling to return the actual
output enable state instead of treating any non-zero value as enabled.
