  * together with the @destroy function,
  * enables driver-specific objects derived from a ttm_buffer_object.
  * On successful return, the object kref and list_kref are set to 1.
+ * If a failure occurs, the function will call the @destroy function, or
+ * kfree() if @destroy is NULL. Thus, after a failure, dereferencing @bo is
