Usually Johannes says he dislike WARNINGs that can be triggered by an existing (faulty) environment, and that WARNINGs should catch internal kernel bugs. So this should not be a WARNING. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
