Subject: [PATCH v2 27/27] crypto: nx - remove stale comment referring to the blkcipher walk API
Date:   Thu, 24 Oct 2019 15:23:45 +0200

These drivers do not use either the deprecated blkcipher or the current
skcipher walk API, so this comment must refer to a previous state of the
driver that no longer exists. So drop the comments.
