From 2ee732d57496b8365819dfb958bc1ff04fcd4cac Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 12 Jul 2016 13:17:59 +0800 Subject: [PATCH] crypto: scatterwalk - Remove unnecessary BUG in scatterwalk_start Nothing bad will happen even if sg->length is zero, so there is no point in keeping this BUG_ON in scatterwalk_start.
