Synopsis
| void edd_release ( | struct kobject * kobj ); | 
 
Arguments
- kobj
- 
     kobject of edd structure
     
Description
   This is called when the refcount of the edd structure
   reaches 0. This should happen right after we unregister,
   but just in case, we use the release callback anyway.
