From 2174a04ee7d8304a270de183fbc58b36dd05b395 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Wed, 30 May 2007 12:57:10 -0500 Subject: [PATCH] [SCSI] iscsi_transport, qla4xxx: have class lookup host for drivers We are going to be adding more host level sysfs attrs and set_params, so this patch has them take a scsi_host instead of either a scsi_host or host no.
