(No action required.)

It's not needed, strictly speaking, but I wonder if it be safer to also
explicitly implement an operator=. (The same applies for FileRef though.)

I think it is okay to not have one right now, given that we don't have a rule to
define class explicitly with either operator=/copy constructor or
DISALLOW_COPY_AND_ASSIGN.

+  virtual ~DeviceRef_Dev();
+
+  PP_DeviceType_Dev GetType() const;
+
+  Var GetName() const;
+};
+
+}  // namespace pp
