From 8cf740ae85df69fb6376f31b42eb2ac7a138721f Mon Sep 17 00:00:00 2001 From: Romain Perier Date: Thu, 28 Jul 2016 11:59:43 +0200 Subject: [PATCH] crypto: marvell - Don't copy IV vectors from the _process op for ciphers The IV output vectors should only be copied from the _complete operation and not from the _process operation, i.e only from the operation that is designed to copy the result of the request to the right location. This copy is already done in the _complete operation, so this commit removes the duplicated code in the _process op. Fixes: 3610d6cd5231 ("crypto: marvell - Add a complete...")
