In file doubango/tinySAK/src/tsk_list.c

do we need check "if (item && item->data)" instead of "if (item)" ? such as:

static tsk_object_t* tsk_list_item_dtor(tsk_object_t *self)
{
        tsk_list_item_t *item = (tsk_list_item_t*)self;
        if(item && item->data){
                item->data = tsk_object_unref(item->data);
        }
        else{
                TSK_DEBUG_WARN("Cannot free an uninitialized item");
        }
        return item;
}
