While we're at this -- shouldn't these all be explicitly declared virtual?

It's not incorrect syntax as it is, just no quite up to style guidelines.

Done.

 
  private:
   // The actual device fd.
   int device_fd_;
 
   // eventfd fd to signal device poll thread when its poll() should be
   // interrupted.
   int device_poll_interrupt_fd_;
 
   DISALLOW_COPY_AND_ASSIGN(ExynosV4L2Device);
