    kernel - Fix IDR bugs
    
    * Allow ptr to be NULL in idr_remove() and idr_replace().
    
    * Note that linux ERR returns from idr_replace() still not implemented
      (requires the related ERR macros to be moved out of drm).  idr_replace()
      still returns NULL when the id cannot be found.
