you can delete the  `nullptr, nullptr`. since you change the function definition as 


```
MMCSectionGOFF *getGOFFSection(StringRef Section, SectionKind Kind,
                                MCSection *Parent = nullptr,
                                const MCExpr *SubsectionId = nullptr);CSection *Parent = nullptr,
const MCExpr *SubsectionId = nullptr)
```
