This causes a crash then whenever async_probe generic module parameter is used. This was overlooked when the form in which in-kernel async probe support was reworked a bit... Fix this as originally intended. Cc: Hannes Reinecke Cc: Dmitry Torokhov Cc: stable@vger.kernel.org (4.2+) Signed-off-by: Luis R.
