I'm inclined to agree, but I'm not completely sure. Why is it OK to have a macro named KVM_PIC, a struct named KVMPICClass, a struct named PICCommonState, but not OK to have a constant named TYPE_KVM_PIC? What about the TYPE_PIC_COMMON constant? All these symbols are internal to the i8259 code and aren't expected to be unique globally. Are TYPE_* names more special and expected to be unique globally? If yes, why?

This will make the type name constant consistent with the name of the type checking macro. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> --- Cc: "Michael S.
