Your for-leds-next branch is based on 6.11-rc1, so it won't apply there. This series does two things: 1. It drops the code for executing MCU commands from the LEDs driver and instead starts using the functions from the turris-omnia-mcu platform driver. This is so that we don't have the same code at two places. 2. It adds support for the global LED brightness change interrupt to the LED driver. This interrupt is exposed by the MCU driver. Userspace can poll for global LED brightness change (triggered by pressing the front button) by polling the corresponding sysfs file, /sys/class/leds//device/brightness, documented in Documentation/ABI/testing/sysfs-class-led-driver-turris-omnia.
