I included this for enums.
But presubmit error on this line. It complains

You added one or more #includes that violate checkdeps rules.
  chromeos/display/real_output_configurator_delegate.h
      Illegal include: "ppapi/c/private/ppb_output_protection_private.h"
    Because of no rule applying.

How to fix this?
