leds: Replace all non-returning strlcpy with strscpy

2026-01-19T12:09:19+00:00

[ Upstream commit bf4a35e9201d30b63a8d276797d6ecfaa596ccd3 ] 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: sgm3140: Add missing timer cleanup and flash gpio control

2024-03-26T22:21:31+00:00

[ Upstream commit 205c29887a333ee4b37596e6533373e38cb23947 ] Enabling strobe and then setting brightness to 0 causes the driver to enter invalid state after strobe end timer fires. We should cancel strobe mode resources when changing brightness (aka torch mode).

leds: lm3601x: Don't use mutex after it was destroyed

2022-10-26T10:34:39+00:00

[ Upstream commit 32f7eed0c763a9b89f6b357ec54b48398fc7b99e ] The mutex might still be in use until the devm cleanup callback devm_led_classdev_flash_release() is called. This only happens some time after lm3601x_remove() completed.

fwnode_get_next_available_child_node() bumps a reference counting of a returned variable. We have to balance it whenever we return to the caller.
