This LED output is called "Fan" in the original kernel and connected to GPIO18 (gpiochip 0, pin 18). Here we called it "miqi:green:fan" to stay consistent with the kernel's naming conventions. It's worth noting that without this patch the fan doesn't work at all, risking to make the board overheat.
