For some reason the #if ENABLED(TMC_DEBUG) block was removed in #27901

And the only time get_pwm_scale is used is when TMC_DEBUG is enabled

  #if ENABLED(TMC_DEBUG)

    template<typename TMC>
    void report_polled_driver_data(TMC &st, const TMC_driver_data &data) {
      const uint32_t pwm_scale = get_pwm_scale(st);
