877e91191c leds: leds-mt6323: Adjust return/parameter types in wled get/set callbacks
Clang's kernel Control Flow Integrity (kCFI) is a compiler-based
security mitigation that ensures the target of an indirect function call
matches the expected type of the call and trapping if they do not match
exactly. The warning -Wincompatible-function-pointer-types-strict aims
to catch these issues at compile time, which reveals:

 drivers/leds/leds-mt6323.c:598:49: error: incompatible function pointer types assigning to 'int (*)(struct led_classdev *, enum led_brightness)' from 'int (struct led_classdev *, unsigned int)' [-Werror,-Wincompatible-function-pointer-types-strict]

 2 errors generated.

While 'unsigned int' is ABI compatible with 'enum led_brightness' (hence
no warning from -Wincompatible-function-pointer-types) and the callers
of these callbacks use/pass the values as 'unsigned int', the mismatch
between the prototype and the called function will trip kCFI at runtime.

Change the types in the implementations to match the prototypes, clearing
up the warning and avoiding kCFI failures.

1471d85ffb s390/ctcm: Convert sprintf/snprintf to scnprintf
This LWN article explains the why scnprintf is preferred over snprintf
in general
https://lwn.net/Articles/69419/
Ie. snprintf() returns what *would* be the resulting length, while
scnprintf() returns the actual length.

Note that ctcm_print_statistics() writes the data into the kernel log
and is therefore not suitable for sysfs_emit(). Observable behavior is
not changed, as there may be dependencies.

1cf3d5567f net: hns3: fix strncpy() not using dest-buf length as length issue
Now, strncpy() in hns3_dbg_fill_content() use src-length as copy-length,
it may result in dest-buf overflow.

This patch is to fix intel compile warning for csky-linux-gcc (GCC) 12.1.0
compiler.

The warning reports as below:

hclge_debugfs.c:92:25: warning: 'strncpy' specified bound depends on
the length of the source argument [-Wstringop-truncation]

strncpy(pos, items[i].name, strlen(items[i].name));

hclge_debugfs.c:90:25: warning: 'strncpy' output truncated before
terminating nul copying as many bytes from a string as its length
[-Wstringop-truncation]

strncpy(pos, result[i], strlen(result[i]));

strncpy() use src-length as copy-length, it may result in
dest-buf overflow.

So,this patch add some values check to avoid this issue.

To hide the first dummy 'data' argument on the tracepoint probe events,
the BTF argument array was modified (skip the first argument for tracepoint),
but the '$arg*' meta argument parser missed that.

Fix to increment the argument index if it is tracepoint probe. And decrement
the index when searching the type of the argument.

9e1a1ee93f i2c: ocores: use devm_ managed clks
Smatch complains that:
drivers/i2c/busses/i2c-ocores.c:704 ocores_i2c_probe()
warn: missing unwind goto?

If any wrong occurs in ocores_i2c_of_probe, the i2c->clk needs to be
released. But the function returns directly without freeing the clock.

Fix this by updating the code to use devm_clk_get_optional_enabled()
instead. Use dev_err_probe() where appropriate as well since we are
changing those statements.

501e197a02 hwrng: st - keep clock enabled while hwrng is registered
The st-rng driver uses devres to register itself with the hwrng core,
the driver will be unregistered from hwrng when its device goes out of
scope. This happens after the driver's remove function is called.

However, st-rng's clock is disabled in the remove function. There's a
short timeframe where st-rng is still registered with the hwrng core
although its clock is disabled. I suppose the clock must be active to
access the hardware and serve requests from the hwrng core.

Switch to devm_clk_get_enabled and let devres disable the clock and
unregister the hwrng. This avoids the race condition.

6cb8815f41 crypto: sig - Add interface for sign/verify
Split out the sign/verify functionality from the existing akcipher
interface.  Most algorithms in akcipher either support encryption
and decryption, or signing and verify.  Only one supports both.

As a signature algorithm may not support encryption at all, these
two should be spearated.

For now sig is simply a wrapper around akcipher as all algorithms
remain unchanged.  This is a first step and allows users to start
allocating sig instead of akcipher.

addde1f2c9 crypto: akcipher - Add sync interface without SG lists
The only user of akcipher does not use SG lists.  Therefore forcing
users to use SG lists only results unnecessary overhead.  Add a new
interface that supports arbitrary kernel pointers.

For the time being the copy will be performed unconditionally.  But
this will go away once the underlying interface is updated.

Note also that only encryption and decryption is addressed by this
patch as sign/verify will go into a new interface (sig).
