From 14c93fa239f720b685f0100b1cabb0668aa441f4 Mon Sep 17 00:00:00 2001 From: Corentin Labbe Date: Mon, 6 Jan 2020 20:30:53 +0100 Subject: [PATCH] crypto: sun8i-ce - fix removal of module 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.
