Hi,
You are correct, there is a bug. But I think your fix is not correct. Here is what I think it's better:

}
Does this solve your problem ?
If you wish I can add you to the commit with your sign-off , if you provide me your email/name, in the form :

checking for CONFIG_LED_x_NONE seems to have the same issues than LED_B_NONE. That is also defined when the LED is set to "No LED on board".
Checking for the existance of LED_x_PIO still feels right as those are only defined if any of the CONFIG_LED_x_ON_PIOn is selected.
You do make sense. I thought more about it, and if we are using PIO calls, makes sense to check for PIO config. Do you wish to add your name to your patch ?
Yes, you can add my name for the patch. Do I need to do something else?

Patched applied and pushed out. Thanks !
For our SAMA5D27 project that is based on SAMA5D27SOM1EK I wanted to unselct the use of the blue LED as we only have 2 LEDs connected but that causes compile errors in driver/led.c
CC driver/led.c driver/led.c: In function ‘at91_leds_init’: driver/led.c:53:22: error: ‘LED_B_PIO’ undeclared (first use in this function); did you mean ‘LED_G_PIO’? 53 | pio_set_gpio_output(LED_B_PIO, CONFIG_LED_B_VALUE); | ^

I fixed in on my end by doing a different check. Patch file attached. at91bootstrap3-v4.0.0-fix-skipping-unselected-leds.patch.txt
