leds: Replace all non-returning strlcpy with strscpy strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.

leds: flash: mt6360: Fix device_for_each_child_node() refcounting in error paths stable inclusion from stable-6.6.64 commit 4a44bcb73a0ba4b4f46b6e89a7755aaaaeb041b1 category: bugfix issue: #IBE7K0 CVE: NA Signed-off-by: zyf1116 <zhouyongfei3@huawei.com> --------------------------------------- commit 73b03b27736e440e3009fe1319cbc82d2cd1290c upstream. The device_for_each_child_node() macro requires explicit calls to fwnode_handle_put() upon early exits to avoid memory leaks, and in this case the error paths are handled after jumping to 'out_flash_realease', which misses that required call to to decrement the refcount of the child node. A more elegant and robust solution is using the scoped variant of the loop, which automatically handles such early exits. Fix the child node refcounting in the error paths by using device_for_each_child_node_scoped().
