Subject: [PATCH v4 27/29] crypto: nx - remove stale comment referring to the blkcipher walk API

From: Ard Biesheuvel <[email-masked]>
Date: Sat, 9 Nov 2019 18:09:52 +0100

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.
