Thank you for the feedback! How would you suggest I go about handling
this? Is there a preferred way to ask the user which way they want to
control the LED (Kconfig?), or should I remove the code for three
separate LEDs entirely? Originally, I didn't delete the code because I
thought it would be bad to remove the existing interface.
