From kay.sievers@vrfy.org Thu Nov 16 21:09:09 2006
From: Kay Sievers <kay.sievers@vrfy.org>
Subject: Driver core: convert ieee1394 subsystem to use struct device
Date: Tue, 24 Oct 2006 18:40:53 +0200
Message-Id: <1161708053.3452.4.camel@pim.off.vrfy.org>
From: Kay Sievers <kay.sievers@vrfy.org>
Converts from using struct "class_device" to "struct device" making
everything show up properly in /sys/devices/ with symlinks from the
/sys/class directory.
