The UVC gadget driver historically uses the
/* Comment
* style
*/
for multi-line block comments, which is frowned upon. Patches for the
driver are required to use the more standard
/*

*/
style. This result in inconsistencies. Fix it by converting all
remaining instances of the old style.

Today's linux-next merge of the extcon tree got a conflict in:
drivers/usb/dwc3/drd.c
between commit:
0f0101719138 ("usb: dwc3: Don't switch OTG -> peripheral if extcon is present")
from the usb tree and commit:
88490c7f43c4 ("extcon: Fix extcon_get_extcon_dev() error handling")

In systemd systems setting a fixed MAC address through
the "dev_addr" module argument fails systematically.
When checking the MAC address after the interface is created
it always has the same but different MAC address to the one
supplied as argument.
This is partially caused by systemd which by default will
set an internally generated permanent MAC address for interfaces
that are marked as having a randomly generated address.
Commit 890d5b40908bfd1a ("usb: gadget: u_ether: fix race in
setting MAC address in setup phase") didn't take into account
the fact that the interface must be marked as having a set
MAC address when it's set as module argument.
Fixed by marking the interface with NET_ADDR_SET when
the "dev_addr" module argument is supplied.

Commit 582ab24e096f ("usb: dwc3: pci: Set "linux,phy_charger_detect"
property on some Bay Trail boards") added a new swnode similar to the
existing ones for boards where the PHY handles charger detection.
Unfortunately, the "linux,sysdev_is_parent" property got lost in the
merge conflict resolution of commit ca9400ef7f67 ("Merge 5.17-rc6 into
usb-next"). Now dwc3_pci_intel_phy_charger_detect_properties is the
only swnode in dwc3-pci that is missing "linux,sysdev_is_parent".
It does not seem to cause any obvious functional issues, but it's
certainly unintended so restore the line to make the properties
consistent again.

The current logic to assign the max packet limit for IN endpoints attempts
to take the default HW value and apply the optimal endpoint settings based
on it. However, if the default value reports a TxFIFO size large enough
for only one max packet, it will divide the value and assign a smaller ep
max packet limit.
For example, if the default TxFIFO size fits 1024B, current logic will
assign 1024/3 = 341B to ep max packet size. If function drivers attempt to
request for an endpoint with a wMaxPacketSize of 1024B (SS BULK max packet
size) then it will fail, as the gadget is unable to find an endpoint which
can fit the requested size.
Functionally, if the TxFIFO has enough space to fit one max packet, it will
be sufficient, at least when initializing the endpoints.

The PC update flags (which also deal with exception injection)
is one of the most complicated use of the flag we have. Make it
more fool prof by:
- moving it over to the new accessors and assign it to the
input flag set
- turn the combination of generic ELx flags with another flag
indicating the target EL itself into an explicit set of
flags for each EL and vector combination
- add a new accessor to pend the exception
This is otherwise a pretty straightformward conversion.

BLAKE2s has no currently known use as an shash. Just remove all of this
unnecessary plumbing. Removing this shash was something we talked about
back when we were making BLAKE2s a built-in, but I simply never got
around to doing it. So this completes that project.
Importantly, this fixs a bug in which the lib code depends on
crypto_simd_disabled_for_test, causing linker errors.
Also add more alignment tests to the selftests and compare SIMD and
non-SIMD compression functions, to make up for what we lose from

HCTR2 is a tweakable, length-preserving encryption mode that is intended
for use on CPUs with dedicated crypto instructions. HCTR2 has the
property that a bitflip in the plaintext changes the entire ciphertext.
This property fixes a known weakness with filename encryption: when two
filenames in the same directory share a prefix of >= 16 bytes, with
AES-CTS-CBC their encrypted filenames share a common substring, leaking
information. HCTR2 does not have this problem.

Karatsuba multiplication is used instead of Schoolbook multiplication
because it was found to be slightly faster on ARM64 CPUs. Montgomery

Add support for HCTR2 as a template. HCTR2 is a length-preserving
encryption mode that is efficient on processors with instructions to
accelerate AES and carryless multiplication, e.g. x86 processors with
AES-NI and CLMUL, and ARM processors with the ARMv8 Crypto Extensions.
As a length-preserving encryption mode, HCTR2 is suitable for
applications such as storage encryption where ciphertext expansion is
not possible, and thus authenticated encryption cannot be used.
Currently, such applications usually use XTS, or in some cases Adiantum.
XTS has the disadvantage that it is a narrow-block mode: a bitflip will
only change 16 bytes in the resulting ciphertext or plaintext. This
reveals more information to an attacker than necessary.
HCTR2 is a wide-block mode, so it provides a stronger security property:
a bitflip will change the entire message. HCTR2 is somewhat similar to
Adiantum, which is also a wide-block mode. However, HCTR2 is designed
to take advantage of existing crypto instructions, while Adiantum
targets devices without such hardware support. Adiantum is also
designed with longer messages in mind, while HCTR2 is designed to be
efficient even on short messages.
HCTR2 requires POLYVAL and XCTR as components. More information on
HCTR2 can be found here: "Length-preserving encryption with HCTR2":

blockcipher mode similar to CTR mode. XCTR uses XORs and little-endian
addition rather than big-endian arithmetic which has two advantages: It
is slightly faster on little-endian CPUs and it is less likely to be
implemented incorrect since integer overflows are not possible on
practical input sizes. XCTR is used as a component to implement HCTR2.

Returning an error value in an i2c remove callback results in an error
message being emitted by the i2c core, but otherwise it doesn't make a
difference. The device goes away anyhow and the devm cleanups are
called.
As atmel_ecc_remove() already emits an error message on failure and the
additional error message by the i2c core doesn't add any useful
information, change the return value to zero to suppress this message.
Also make the error message a bit more drastical because when the device
is still busy on remove, it's likely that it will access freed memory
soon.
This patch is a preparation for making i2c remove callbacks return void.

For some sev ioctl interfaces, input may be passed that is less than or
equal to SEV_FW_BLOB_MAX_SIZE, but larger than the data that PSP
firmware returns. In this case, kmalloc will allocate memory that is the
size of the input rather than the size of the data. Since PSP firmware
doesn't fully overwrite the buffer, the sev ioctl interfaces with the
issue may return uninitialized slab memory.
Currently, all of the ioctl interfaces in the ccp driver are safe, but
to prevent future problems, change all ioctl interfaces that allocate
memory with kmalloc to use kzalloc and memset the data buffer to zero

Commit 680532c50bca ("drm: adv7511: Add support for
i2c_new_secondary_device") allows a device tree node to override
the default addresses of the secondary i2c devices. This is useful
for solving address conflicts on the i2c bus.
In adv7511_init_cec_regmap() the new i2c address of cec device is
read from device tree and immediately accessed, well before it is
written in the proper register to override the default address.
This can cause an i2c error during probe and a consequent probe
failure.
Once the new i2c address is read from the device tree, override
the default address before any attempt to access the cec.
Tested with adv7533 and stm32mp157f.

The HP Omen 15 laptop needs a quirk to toggle the mute LED. It already is implemented for a different variant of the HP Omen laptop so a fixup entry is needed for this variant.

fa84f89395e0 ("irqchip/loongson-liointc: Fix build error for
LoongArch") replaced get_ebase_cpunum with physical processor
id from SMP facilities. However that breaks MIPS non-SMP build
and makes booting from other cores inpossible on non-SMP kernel.
Thus we revert get_ebase_cpunum back and use get_csr_cpuid for
LoongArch.

We would like to make chip_info table const, but 8821c uses one field as
a variable, and causes core dump. To fix this, move the field to another
struct that can be read and written.
