From f6b99b6e18657aa1222b0c51ad20ac674e764281 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Thu, 23 May 2019 10:50:27 +0200 Subject: crypto: caam - print IV only when non NULL Since eaed71a44ad9 ("crypto: caam - add ecb(*) support") the IV can be NULL, so only dump it when it's non NULL as designated by the ivsize variable.
