With Sphinx 1.6 nested numbering is reported as warning::

  ./input/joydev/index.rst:13: WARNING: input/joydev/joystick-api is already assigned section numbers (nested numbered toctree?)
  ./media/uapi/cec/cec-funcs.rst:8: WARNING: media/uapi/cec/cec-func-open is already assigned section numbers (nested numbered toctree?)

TOC numbering is already set in::

  ./input/devices/index.rst:9:
  ./media/uapi/cec/cec-api.rst:19:

I guess the nested numbering in:

  ./input/joydev/index.rst
  ./media/uapi/cec/cec-funcs.rst

is just a C&P typo, so lets remove it.
