From f4e91eb4a81559da87a3843758a641b5cc590b65 Mon Sep 17 00:00:00 2001 From: Tony Jones Date: Fri, 22 Feb 2008 00:13:36 +0100 Subject: IB: convert struct class_device to struct device This converts the main ib_device to use struct device instead of struct class_device as class_device is going away.
