The continuous PWM voltage regulator is caching the voltage value in the ->volt_uV field. While most of the time this value should reflect the real voltage, sometime it can be sightly different if the PWM device rounded the set_duty_cycle request. Moreover, this value is not valid until someone has modified the regulator output.
