The static code scanner "Parfait" reported this because pwm_config is
only 3 bytes - pwm_config[3] is out of range. Since this code path is
never called with ix == 3 (the device has no PWM4 output) this doesn't
change anything in practice. But to encourage testing with Parfait, lets
make the warning go away...
