From 05321937469a8592d6a6d35f1d38ca882d243044 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 6 Mar 2008 00:13:36 +0100 Subject: [PATCH] IB: rename "dev" to "srp_dev" in srp_host structure This sets us up to be able to convert the srp_host to use a struct device instead of a class_device. Based on a original patch from Tony Jones, but split up into this piece by Greg.
