Hello Lee,

this series is for 6.12, but it depends on changes that have been
merged to 6.11-rc3. 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/<led>/device/brightness, documented in
   Documentation/ABI/testing/sysfs-class-led-driver-turris-omnia.
