Add USB device ID (04ca:3807) for a Lite-On Wireless_Device containing
a MediaTek MT7921 (MT7920) Bluetooth chipset found in Acer laptops.
Without this entry, btusb binds via the generic USB class-based wildcard
match but never sets the BTUSB_MEDIATEK flag. This means btmtk never
triggers firmware loading, and the driver sends a raw HCI Reset that
the uninitialized chip cannot respond to, resulting in:
Bluetooth: hci0: Opcode 0x0c03 failed: -110
The information in /sys/kernel/debug/usb/devices about the Bluetooth
device is listed as the below:

The BT core skips calling the hci_dev's shutdown method when the HCI
is unregistered. This means that qca_power_off() was not getting called
leaving BT powered on.
This causes regulators / pwrseq providers to not get disabled which also
causes problem when re-loading the module because regulators and pwrseq
providers have an enablecount which now has never dropped to 0, causing
the BT to not get properly reset between rmmod and re-load which causes
initialization failure on the re-load.
Fix this by calling qca_power_off() from qca_close() when BT has not
already been powered off through a qca_hci_shutdown() call.
hci_ldisc.c will call qca_close() after freeing the hdev, so this
means that qca_power_off() can now no longer deref hu->hdev, change
the logging in qca_power_off() to no longer use hu->hdev.

The function called qca_power_off() is actually the hci_dev shutdown
handler, rename it to qca_hci_shutdown() to make this clear.
While the qca_power_shutdown() function is actually the counter-part
of qca_power_on() rename it to qca_power_off() to make this clear.

removal
CXL is linked before fwctl in drivers/Makefile. Both use `module_init, so
`cxl_pci_driver_init()` runs first. When `cxl_pci_probe()` calls
`fwctl_register()` and then `device_add()`, fwctl_class is not yet
registered because fwctl_init() hasn't run, causing `class_to_subsys()` to
return NULL and skip knode_class initialization.
On device removal, `class_to_subsys()` returns non-NULL, and
`device_del()` calls `klist_del()` on the uninitialized knode, triggering
a NULL pointer dereference.

Add a con_id parameter to skl_int3472_register_led() to allow callers
to specify both the LED name suffix and lookup con_id instead of
hardcoding "privacy". This prepares for registering additional LED
types with different names.
While at it, rename the privacy LED's GPIO con_id from "privacy-led"
to "privacy" in int3472_get_con_id_and_polarity() and pass it
directly to skl_int3472_register_led(), reducing churn when adding
new LED types.

In passthrough mode, dm-cache defers write submission until after
metadata commit completes via the invalidate_committed() continuation.
On commit error, invalidate_committed() calls invalidate_complete() to
end the bio and free the migration struct, after which it should return
immediately.
The patch 4ca8b8bd952d ("dm cache: fix write hang in passthrough mode")
omitted this early return, causing execution to fall through into the
success path on error. This results in use-after-free on the migration
struct in the subsequent calls.
Fix by adding the missing return after the invalidate_complete() call.

Currently, if perf_l2_init() fails turbostat exits after issuing the
following error (which was encountered on AlderLake):
turbostat: perf_l2_init(cpu0, 0x0, 0xff24) REFS: Invalid argument
This occurs because perf_l2_init() calls err(). However, the code has been
written in such a manner that it is able to perform cleanup and continue.
Therefore, this issue can be addressed by changing the appropriate calls
to err() to warnx().
Additionally, correct the PMU type arguments passed to the warning strings
in the ecore and lcore blocks so the logs accurately reflect the failing
counter type.

snd_wss_resume() restores only the codec register image. The SC-6000
driver also programs card-specific DSP routing and enters MSS mode
during probe, and that setup is not replayed after suspend.
Cache the WSS chip pointer in the SC-6000 card state and wire ISA
suspend and resume callbacks to the shared board-programming helper,
so the board is reinitialized before the codec state is restored.
This keeps the old/new DSP split in one place and restores the
board-level MSS setup that the codec resume path does not cover.

The driver may auto-select IRQ and DMA resources at probe time, but
sc6000_init_board() still derives the SC-6000 soft configuration from
the module parameter arrays. When irq=auto or dma=auto is used, the
codec is created with the selected resources while the board is
programmed with the unresolved values.
Store the mapped ports and generated SC-6000 board configuration in
card-private data, build that configuration from the live probe
results instead of the raw module parameters, and keep the probe-time
board programming in a shared helper.
This fixes the resource-programming mismatch and leaves the driver
with a stable board-state block that can be reused by suspend/resume.

In usb6fire_chip_abort(), the chip struct is allocated as the card's
private data (via snd_card_new with sizeof(struct sfire_chip)). When
snd_card_free_when_closed() is called and no file handles are open, the
card and embedded chip are freed synchronously. The subsequent
chip->card = NULL write then hits freed slab memory.
Call trace:
usb6fire_chip_abort sound/usb/6fire/chip.c:59 [inline]
usb6fire_chip_disconnect+0x348/0x358 sound/usb/6fire/chip.c:182
usb_unbind_interface+0x1a8/0x88c drivers/usb/core/driver.c:458
...
hub_event+0x1a04/0x4518 drivers/usb/core/hub.c:5953
Fix by moving the card lifecycle out of usb6fire_chip_abort() and into
usb6fire_chip_disconnect(). The card pointer is saved in a local
before any teardown, snd_card_disconnect() is called first to prevent
new opens, URBs are aborted while chip is still valid, and
snd_card_free_when_closed() is called last so chip is never accessed
after the card may be freed.

The status field in an EFW response is a 32-bit value supplied by the
firewire device. efr_status_names[] has 17 entries so a status value
outside that range goes off into the weeds when looking at the %s value.
Even worse, the status could return EFR_STATUS_INCOMPLETE which is
0x80000000, and is obviously not in that array of potential strings.
Fix this up by properly bounding the index against the array size and
printing "unknown" if it's not recognized.

A malicious USB device with the TASCAM US-144MKII device id can have a
configuration containing bInterfaceNumber=1 but no interface 0. USB
configuration descriptors are not required to assign interface numbers
sequentially, so usb_ifnum_to_if(dev, 0) returns will NULL, which will
then be dereferenced directly.
Fix this up by checking the return value properly.

When reporting the pointer for a compressed stream we report the current
I/O frame position by dividing the position by the number of channels
multiplied by the number of container bytes. These values default to 0 and
are only configured as part of setting the stream parameters so this allows
a divide by zero to be configured. Validate that they are non zero,
returning an error if not

mtk_snand_probe() registers the on-host NAND ECC engine, but teardown was
missing from both probe unwind and remove-time cleanup. Add a devm cleanup
action after successful registration so
nand_ecc_unregister_on_host_hw_engine() runs automatically on probe
failures and during device removal.

A change moving DMA channel allocation from probe() back to
s3c64xx_spi_prepare_transfer() failed to remove the corresponding
deallocation from remove().
Drop the bogus DMA channel release from remove() to avoid triggering a
NULL-pointer dereference on driver unbind.
This issue was flagged by Sashiko when reviewing a controller
deregistration fix.

The bounds checking in scsi_bsg_uring_cmd() does not work because
cmd->request_len is a u32 and scmd->cmd_len is a u16. We check that
scmd->cmd_len is valid but if the cmd->request_len is more than
USHRT_MAX it would still lead to a buffer overflow when we do the
copy_from_user().

Johan Hovold <johan@kernel.org> says:
Device managed registration generally only works if all involved
resources are managed as otherwise resources may be disabled or freed
while they are still in use.
This series fixes the SPI controller drivers that get this wrong by
disabling resources such as clocks, DMA and interrupts while the
controller (and its devices) are still registered, which can lead to
issues like system errors due to unclocked accesses, NULL-pointer
dereferences, hangs or just prevent SPI device drivers from doing I/O
during during deregistration (e.g. to power down devices).
I decided to split these fixes in two parts consisting of 20 and 26
patches respectively in order not to spam the lists too much.
I've also prepared a follow-on series to convert the drivers here that
do not yet use device managed controller allocation (which avoids taking
extra references during deregistration).
After that it should be possible to change the SPI API so that it no
longer drops a reference during deregistration without too much effort
(cf. [1]).
Note that this series is based on spi/for-next which specifically has
commit 1f8fd9490e31 ("spi: zynq-qspi: Simplify clock handling with
devm_clk_get_enabled()") (which is not in the for-7.1 branch).

Make sure to deregister the controller before disabling it during driver
unbind.
Note that clocks were also disabled before the recent commit
1f8fd9490e31 ("spi: zynq-qspi: Simplify clock handling with
devm_clk_get_enabled()").
