From dd7f2928d834f7ac67202bcdf24a44ba9b138f08 Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Fri, 25 May 2007 11:50:53 +0200 Subject: [PATCH] ieee1394: convert ieee1394 from "struct class_device" to "struct device" Here is a straightforward conversion to "struct device". The "struct class_device" will be removed from the kernel. It seems to work fine for me with and without CONFIG_SYSFS_DEPRECATED set.
