Do you mean I should update it as below? Seems there is no consumer to 
use the function config, do we need to add now?
pm8350c_pwm {
  +       function = LED_FUNCTION_STATUS;
  +       #address-cells = <1>;
  +       #size-cells = <0>;
  +       status = "okay";
  +
  +       led@1 {
  +               reg = <1>;
  +               color = <LED_COLOR_ID_RED>;
  +		 function = LED_FUNCTION_STATUS;
  +       };
  + ...
