From 0e22a2d18998fd183c8181663981eb681ca977e9 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Thu, 30 May 2013 16:14:44 +0200 Subject: vhost-scsi: fix k->set_guest_notifiers() NULL dereference Coverity picked up a copy-paste bug. In vhost_scsi_start() we check for !k->set_guest_notifiers and error out. The check probably got copied but instead of erroring we actually use the function pointer!
