I am actually in doubt that original commit message provides that short period
intentionally. Possibly it was misinterpretation of nanoseconds (which is
expected by PWM framework) with microseconds than might sound logical for LED.
Perhaps we may add 000 to the value (1) and replace us by ms in the text (2).
