wiphy_unregister()/wiphy_free() has been recently decoupled from
wilc_netdev_cleanup() to fix a faulty error path in sdio/spi probe
functions. However this change introduced a new failure when simply
loading then unloading the driver:

The warning is triggered by the fact that there is still a
wireless_device linked to the wiphy we are unregistering, due to
wiphy_unregister() now being called after net device unregister (performed
in wilc_netdev_cleanup()). Fix this warning by moving wiphy_unregister()
after wilc_netdev_cleanup() is nominal paths (ie: driver removal).
wilc_netdev_cleanup() ordering is left untouched in error paths in probe
function because net device is not registered in those paths (so the
warning can not trigger), yet the wiphy can still be registered, and we
still some cleanup steps from wilc_netdev_cleanup().

The futex operation FUTEX_OP_ANDN is supposed to implement
*(int *)UADDR2 &= ~OPARG;
The s390 implementation just implements an AND instead of ANDN.
Add the missing bitwise not operation to oparg to fix this.
This is broken since nearly 19 years, so it looks like user space is
not making use of this operation.

The new option controls tests run on boot or module load. With the new
debugfs "run" dentry allowing to run tests on demand, an ability to disable
automatic tests run becomes a useful option in case of intrusive tests.
The option is set to true by default to preserve the existent behavior. It
can be overridden by either the corresponding module option or by the
corresponding config build option.

The SQ and CQ ring heads are read twice - once for verifying that it's
within bounds, and once inside the loops copying SQE and CQE entries.
This is technically incorrect, in case the values could get modified
in between verifying them and using them in the copy loop. While this
won't lead to anything truly nefarious, it may cause longer loop times
for the copies than expected.
Read the ring head values once, and use the verified value in the copy
loops.

For WCN6855, board ID specific NVM needs to be downloaded once board ID
is available, but the default NVM is always downloaded currently.
The wrong NVM causes poor RF performance, and effects user experience
for several types of laptop with WCN6855 on the market.
Fix by downloading board ID specific NVM if board ID is available.

The hdev->reset is never used now and the hdev->cmd_timeout actually
does reset. This patch changes the call path from
hdev->cmd_timeout -> vendor_cmd_timeout -> btusb_reset -> hdev->reset
, to
hdev->reset -> vendor_reset -> btusb_reset
Which makes it clear when we export the hdev->reset to a wider usage
e.g. allowing reset from sysfs.
This patch doesn't introduce any behavior change.

Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read. Ternary
operator has three arguments and with wrapping might lead to quite
long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary
file.

A NULL sock pointer is passed into l2cap_sock_alloc() when it is called
from l2cap_sock_new_connection_cb() and the error handling paths should
also be aware of it.
Seemingly a more elegant solution would be to swap bt_sock_alloc() and
l2cap_chan_create() calls since they are not interdependent to that moment
but then l2cap_chan_create() adds the soon to be deallocated and still
dummy-initialized channel to the global list accessible by many L2CAP
paths. The channel would be removed from the list in short period of time
but be a bit more straight-forward here and just check for NULL instead of
changing the order of function calls.
Found by Linux Verification Center (linuxtesting.org) with SVACE static
analysis tool.

The firmware-name property has been expanded to specify the names of NVM
and rampatch firmware for certain chips, such as the QCA6698 Bluetooth
chip. Although it shares the same IP core as the WCN6855, the QCA6698
has different RF components and RAM sizes, necessitating new firmware
files. This change allows for the configuration of NVM and rampatch in
DT.
Possible configurations:
firmware-name = QCA6698/hpnv21.bin, QCA6698/hpbtfw21.tlv;
firmware-name = QCA6698/hpnv21, QCA6698/hpbtfw21.tlv;

It can be a bit hard to tell which parts of io_register_resize_rings()
are operating on shared memory, and which ones are not. And anything
reading or writing to those regions should really use the read/write
once primitives.
Hence add those, ensuring sanity in how this memory is accessed, and
helping document the shared nature of it.

Different connectivity boards may be attached to the same platform. For
example, QCA6698-based boards can support either a two-antenna or
three-antenna solution, both of which work on the sa8775p-ride platform.
Due to differences in connectivity boards and variations in RF
performance from different foundries, different NVM configurations are
used based on the board ID.
Therefore, in the firmware-name property, if the NVM file has an
extension, the NVM file will be used. Otherwise, the system will first
try the .bNN (board ID) file, and if that fails, it will fall back to
the .bin file.
Possible configurations:
firmware-name = "QCA6698/hpnv21";
firmware-name = "QCA6698/hpnv21.bin";

Expand the firmware-name property to specify the names of NVM and
rampatch firmware to load. This update will support loading specific
firmware (nvm and rampatch) for certain chips, like the QCA6698
Bluetooth chip, which shares the same IP core as the WCN6855 but has
different RF components and RAM sizes, requiring new firmware files.
We might use different connectivity boards on the same platform. For
example, QCA6698-based boards can support either a two-antenna or
three-antenna solution, both of which work on the sa8775p-ride platform.
Due to differences in connectivity boards and variations in RF
performance from different foundries, different NVM configurations are
used based on the board ID.
So In firmware-name, if the NVM file has an extension, the NVM file will
be used. Otherwise, the system will first try the .bNN (board ID) file,
and if that fails, it will fall back to the .bin file.
Possible configurations:
firmware-name = "QCA6698/hpnv21.bin", "QCA6698/hpbtfw21.tlv";
firmware-name = "QCA6698/hpnv21", "QCA6698/hpbtfw21.tlv";
firmware-name = "QCA6698/hpnv21.bin";

connection changes are not dispatched to the hci_event module, and
the underlying Bluetooth controller's USB Interface 1 will not be

Normally the kernel would not expect an application to modify any of
the data shared with the kernel during a resize operation, but of
course the kernel cannot always assume good intent on behalf of the
application.
As part of resizing the rings, existing SQEs and CQEs are copied over
to the new storage. Resizing uses the masks in the newly allocated
shared storage to index the arrays, however it's possible that malicious
userspace could modify these after they have been sanity checked.
Use the validated and locally stored CQ and SQ ring sizing for masking
to ensure the values are both stable and valid.
Fixes: 79cfe9e59c2a ("io_uring/register: add IORING_REGISTER_RESIZE_RINGS")

KEY_CAMERA_ACESS
Use SW_CAMERA_LENS_COVER instead of KEY_CAMERA_ACESS_ENABLE and
KEY_CAMERA_ACESS_DISABLE. When the camera toggle switch was hit,
the lenovo-wmi-camera driver would report an event code.

Currently the choices for the platform profile are hardcoded. There is
an ACPI bitmap accessible via WMI that specifies the supported profiles,
use this bitmap to dynamically set the choices for the platform profile.

Make use of platform_profile_cycle() to simplify the logic used for
cycling through the different platform profiles. Also remove the
unnecessary handling for AC power, as the hardware accepts different
profiles regardless of whether AC is plugged in.

Improve the platform profile handling by using WMI calls to fetch the
current platform profile instead of directly accessing it from the EC.
This is beneficial because the EC address differs for certain laptops.

The F11 key on the new Lenovo Thinkpad T14 Gen 5, T16 Gen 3, and P14s
Gen 5 laptops includes a symbol showing a smartphone and a laptop
chained together. According to the user manual, it starts the Microsoft
Phone Link software used to connect to Android/iOS devices and relay
messages/calls or sync data.
These laptops send the 0x1320 hkey event when the key is pressed. Map
this event to the new KEY_LINK_PHONE keycode.
