Hi Pavel, We have running systems that use COLOR_ID_MULTI. The GPIO toggles between two colors and we have used the identifier. RGB is not a good fit since it is not a RGB LED. Please provide guidance. This patch causes the system to not start: f741121a2251 leds: Fix BUG_ON check for LED_COLOR_ID_MULTI that is always false It was also backported to stable causing previously booting systems to no longer boot. Best, Da Xue
