is there any easy change I could make there to fix only the stuck LEDs of SMondial A and AB?
(no need for any other of your improvements like tri-color LEDs etc. ...)
Not easy.
The way the LED outputs were done in the old driver is nonsense from a hardware point of view and needed a complete rewrite.
It needs to use pwm_display_device to get correct leds.
