a31e4518be fbdev: udlfb: avoid divide-by-zero on FBIOPUT_VSCREENINFO
Much like commit 19f953e743 ("fbdev: fb_pm2fb: Avoid potential divide
by zero error"), we also need to prevent that same crash from happening
in the udlfb driver as it uses pixclock directly when dividing, which
will crash.

b7feba842c ALSA: interwave: guard PM-only restore helpers with CONFIG_PM
The InterWave PM patch added snd_interwave_restore_regs() and
snd_interwave_restore_memory() as static helpers, but both are used only
from the resume path under CONFIG_PM.

On configurations without CONFIG_PM, such as alpha allyesconfig, this
leaves both helpers unused and triggers -Wunused-function warnings with
W=1.

Move the PM-only helpers into the existing CONFIG_PM section. Keep
__snd_interwave_restore_regs() outside the guard because it is also used
during probe-time initialization.

52521e8398 ALSA: usb-audio: Evaluate packsize caps at the right place
We introduced the upper bound checks of the packet sizes by the
ep->maxframesize for avoiding the URB submission errors.  However, the
check was applied at an incorrect place in the function
snd_usb_endpoint_set_params() where ep->maxframesize isn't defined
yet; the value is defined at a bit later position.  So this ended up
with a failure at the first run while the second run works.

For fixing it, move the check at the correct place, right after the
calculation of ep->maxframesize in the same function.

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:

9ff5ff0b91 Bluetooth: hci_qca: Fix BT not getting powered-off on rmmod
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.

a55f80233f fwctl: Fix class init ordering to avoid NULL pointer dereference on device 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.

Fixes: 858ce2f56b ("cxl: Add FWCTL support to CXL")

platform/x86: int3472: Parameterize LED con_id in registration
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.

No functional change.

8c0ee19db8 dm cache: fix missing return in invalidate_committed's error path
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 4ca8b8bd95 ("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.

Fixes: 4ca8b8bd95 ("dm cache: fix write hang in passthrough mode")
