From f2ac67746534fab0cbc0bc29bfc3e507b1f58474 Mon Sep 17 00:00:00 2001 From: Horia Geantă Date: Wed, 1 Nov 2017 09:13:10 +0200 Subject: crypto: caam - remove unneeded edesc zeroization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extended descriptor allocation has been changed by commit dde20ae9d6383 ("crypto: caam - Change kmalloc to kzalloc to avoid residual data") to provide zeroized memory, meaning we no longer have to sanitize its members - edesc->src_nents and edesc->dst_dma.
