coding style:
- there is a useless empty line before "public:"
- "public:" should not be indented.

Done.

+        virtual ~PushPermissionCallback();
+
+        // Called if the embedder is able to check the status of the push permission.

nit: I would put those comments in WebPushPermissionCallback and just point that
those methods are implementing the interface.

[Miguel Garcia, 2014/10/20 09:58:10]

Done.

+
+        // Called if for some reason the status of the push permission cannot be checked.
+        virtual void onError() override;

Could you move that in an anonymous namespace in the cpp file?

+        RefPtr<ScriptPromiseResolver> m_resolver;
+};

+} // namespace blink
