Subject[PATCH 5.5 176/367] crypto: sun8i-ce - fix removal of module
Date
From: Corentin Labbe <clabbe.montjoie@gmail.com>

commit 93d24ac4b26770f8e5118a731cd9314f3808bd10 upstream.

Removing the driver cause an oops due to the fact we clean an extra
channel.
Let's give the right index to the cleaning function.

Fixes: 06f751b61329 ("crypto: allwinner - Add sun8i-ce Crypto Engine")
