Subject: [PATCH 1/2] kernel-doc: Handle function typedefs that return pointers

From: Eduardo Habkost <ehabkost@...hat.com>

One example that was not being parsed correctly by kernel-doc is:

  typedef Object *(ObjectPropertyResolve)(Object *obj,
                                          void *opaque,
                                          const char *part);
