From 77cca462c69d827fabee0ef3fdab86109c2fe8d8 Mon Sep 17 00:00:00 2001 From: James Smart Date: Fri, 21 Mar 2008 17:18:23 -0400 Subject: [SCSI] hosts.c: fixes for "no error" reported after error scenarios This patch corrects some cases in scsi_add_host() that fail, but the "error" return code was not reset after a prior use which set it to a non-error value.
