ALSA: hda/realtek: Support mute LED on HP Laptop 15s-du3xxx
commit 35ef1c79d2e09e9e5a66e28a66fe0df4368b0f3d upstream.
The mute LED on this HP laptop uses ALC236 and requires a quirk to function.
This patch enables the existing quirk for the device.
Tested on my laptop and the LED behaviour works as intended.

ALSA: usb-audio: Add quirk for Plantronics headsets to fix control names
commit 486f6205c233da1baa309bde5f634eb1f8319a33 upstream.
Many Poly/Plantronics headset families name the feature, input,
and/or output units in a such a way to produce control names
that are not recognized by user space. As such, the volume and
mute events do not get routed to the headset's audio controls.
As an example from a product family:
The microphone mute control is named
Headset Microphone Capture Switch
and the headset volume control is named
Headset Earphone Playback Volume
The quirk fixes these to become
Headset Capture Switch
Headset Playback Volume

ARM: 9350/1: fault: Implement copy_from_kernel_nofault_allowed()
commit 169f9102f9198b04afffa6164372a4ba4070f412 upstream.
Under PAN emulation when dumping backtraces from things like the
LKDTM EXEC_USERSPACE test[1], a double fault (which would hang a CPU)
would happen because of dump_instr() attempting to read a userspace
address. Make sure copy_from_kernel_nofault() does not attempt this
any more.

ARM: dts: imx6qdl-apalis: Fix poweroff on Apalis iMX6
commit 83964a29379cb08929a39172780a4c2992bc7c93 upstream.
The current solution for powering off the Apalis iMX6 is not functioning
as intended. To resolve this, it is necessary to power off the
vgen2_reg, which will also set the POWER_ENABLE_MOCI signal to a low
state. This ensures the carrier board is properly informed to initiate
its power-off sequence.
The new solution uses the regulator-poweroff driver, which will power
off the regulator during a system shutdown.

atm: Fix NULL pointer dereference
commit bf2986fcf82a449441f9ee4335df19be19e83970 upstream.
When MPOA_cache_impos_rcvd() receives the msg, it can trigger
Null Pointer Dereference Vulnerability if both entry and
holding_time are NULL. Because there is only for the situation
where entry is NULL and holding_time exists, it can be passed
when both entry and holding_time are NULL. If these are NULL,
the entry will be passd to eg_cache_put() as parameter and
it is referenced by entry->use code in it.

commit c0c9c73434666dc99ee156b25e7e722150bee001 upstream.

counter: stm32-lptimer-cnt: fix error handling when enabling
commit 8744dcd4fc7800de2eb9369410470bb2930d4c14 upstream.
In case the stm32_lptim_set_enable_state() fails to update CMP and ARR,
a timeout error is raised, by regmap_read_poll_timeout. It may happen,
when the lptimer runs on a slow clock, and the clock is gated only
few times during the polling.
Badly, when this happen, STM32_LPTIM_ENABLE in CR register has been set.
So the 'enable' state in sysfs wrongly lies on the counter being
correctly enabled, due to CR is read as one in stm32_lptim_is_enabled().
To fix both issues:
- enable the clock before writing CMP, ARR and polling ISR bits. It will
avoid the possible timeout error.
- clear the ENABLE bit in CR and disable the clock in the error path.

HID: hid-plantronics: Add mic mute mapping and generalize quirks
commit 9821709af892be9fbf4ee9a50b2f3e0604295ce0 upstream.
Add mapping for headset mute key events.
Remove PLT_QUIRK_DOUBLE_VOLUME_KEYS quirk and made it generic.
The quirk logic did not keep track of the actual previous key
so any key event occurring in less than or equal to 5ms was ignored.
Remove PLT_QUIRK_FOLLOWED_OPPOSITE_VOLUME_KEYS quirk.
It had the same logic issue as the double key quirk and was actually
masking the as designed behavior of most of the headsets.
It's occurrence should be minimized with the ALSA control naming
quirk that is part of the patch set.

media: i2c: et8ek8: Don't strip remove function when driver is builtin
commit 545b215736c5c4b354e182d99c578a472ac9bfce upstream.
Using __exit for the remove function results in the remove callback
being discarded with CONFIG_VIDEO_ET8EK8=y. When such a device gets
unbound (e.g. using sysfs or hotplug), the driver is just removed
without the cleanup being performed. This results in resource leaks. Fix
it by compiling in the remove callback unconditionally.
This also fixes a W=1 modpost warning:
WARNING: modpost: drivers/media/i2c/et8ek8/et8ek8: section mismatch in reference: et8ek8_i2c_driver+0x10 (section: .data) -> et8ek8_remove (section: .exit.text)

net: usb: usbnet: restore usb%d name exception for local mac addresses
commit 2ea396448f26d0d7d66224cb56500a6789c7ed07 upstream.
commit 8a7d12d674ac ("net: usb: usbnet: fix name regression") assumed
that local addresses always came from the kernel, but some devices hand
out local mac addresses so we ended up with point-to-point devices with
a mac set by the driver, renaming to eth%d when they used to be named
usb%d.
Userspace should not rely on device name, but for the sake of stability
restore the local mac address check portion of the naming exception:
point to point devices which either have no mac set by the driver or
have a local mac handed out by the driver will keep the usb%d name.
(some USB LTE modems are known to hand out a stable mac from the locally
administered range; that mac appears to be random (different for
mulitple devices) and can be reset with device-specific commands, so
while such devices would benefit from getting a OUI reserved, we have
to deal with these and might as well preserve the existing behavior
to avoid breaking fragile openwrt configurations and such on upgrade.)

netfilter: socket: Lookup orig tuple for IPv6 SNAT
commit 932b32ffd7604fb00b5c57e239a3cc4d901ccf6e upstream.
nf_sk_lookup_slow_v4 does the conntrack lookup for IPv4 packets to
restore the original 5-tuple in case of SNAT, to be able to find the
right socket (if any). Then socket_match() can correctly check whether
the socket was transparent.
However, the IPv6 counterpart (nf_sk_lookup_slow_v6) lacks this
conntrack lookup, making xt_socket fail to match on the socket when the
packet was SNATed. Add the same logic to nf_sk_lookup_slow_v6.
IPv6 SNAT is used in Kubernetes clusters for pod-to-world packets, as
pods' addresses are in the fd00::/8 ULA subnet and need to be replaced
with the node's external address. Cilium leverages Envoy to enforce L7
policies, and Envoy uses transparent sockets. Cilium inserts an iptables
prerouting rule that matches on `-m socket --transparent` and redirects
the packets to localhost, but it fails to match SNATed IPv6 packets due
to that missing conntrack lookup.

usb: gadget: uvc: Fix ERR_PTR dereference in uvc_v4l2.c
commit a7bb96b18864225a694e3887ac2733159489e4b0 upstream.
Fix potential dereferencing of ERR_PTR() in find_format_by_pix()
and uvc_v4l2_enum_format().
Fix the following smatch errors:
drivers/usb/gadget/function/uvc_v4l2.c:124 find_format_by_pix()
error: 'fmtdesc' dereferencing possible ERR_PTR()
drivers/usb/gadget/function/uvc_v4l2.c:392 uvc_v4l2_enum_format()
error: 'fmtdesc' dereferencing possible ERR_PTR()
Also, fix similar issue in uvc_v4l2_try_format() for potential
dereferencing of ERR_PTR().

usb: typec: ucsi: Fix NULL pointer access
commit b13abcb7ddd8d38de769486db5bd917537b32ab1 upstream.
Resources should be released only after all threads that utilize them
have been destroyed.
This commit ensures that resources are not released prematurely by waiting
for the associated workqueue to complete before deallocating them.
