From 45943a58df46b912685af26000e4dbacddd9c567 Mon Sep 17 00:00:00 2001 From: Stephan Mueller Date: Sun, 17 Aug 2014 17:38:29 +0200 Subject: [PATCH] crypto: drbg - remove superflowous checks The crypto_init and crypto_fini functions are always implemented. Thus, there is no need for a protecting check.
