From 1d9fd24206b274e4adf1e88dd48c781692e983c5 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 22 Jul 2015 18:05:35 +0800 Subject: [PATCH] crypto: ixp4xx - Remove bogus BUG_ON on scattered dst buffer commit f898c522f0e9ac9f3177d0762b76e2ab2d2cf9c0 upstream. This patch removes a bogus BUG_ON in the ablkcipher path that triggers when the destination buffer is different from the source buffer and is scattered.
