Merge tag 'leds-next-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds
PULL LED updates from Lee Jones:
- Remove unused local header files from various drivers
- Revert platform driver removal to the original method for consistency
- Introduce ordered workqueues for LED events, replacing the less
efficient system_wq
- Switch to a safer iteration macro in several drivers to prevent
potential memory leaks
- Fix a refcounting bug in the mt6360 flash LED driver
- Fix an uninitialized variable in the mt6370_mc_pattern_clear()
function
- Resolve Smatch warnings in the leds-bcm6328 driver
- Address a potential NULL pointer dereference in the brightness_show()
function
- Fix an incorrect format specifier in the ss4200 driver
- Prevent a resource leak in the max5970 driver's probe function
- Add support for specifying the number of serial shift bits in the
device tree for the BCM63138 family
- Implement multicolor brightness control in the lp5562 driver
- Add a device tree property to override the default LED pin polarity
- Add a property to specify the default brightness value when the LED
is initially on
- Set missing timing properties for the ktd2692 driver
- Document the "rc-feedback" trigger for controlling LEDs based on
remote control activity
- Convert text bindings to YAML for the pca955x driver to enable device
tree validation
- Remove redundant checks for invalid channel numbers in the lp55xx
driver
- Update the MAINTAINERS file with current contact information
