9. Switch to standard V4L2 sub-device API for sensor and lens. In

   particular, the user space API needs to support V4L2 controls as

   defined in the V4L2 spec and references to atomisp must be removed from

   these drivers.



10. Use LED flash API for flash LED drivers such as LM3554 (which already

    has a LED class driver).
