[PATCH] driver core: restore event order for device_add()
Kay Sievers [Mon, 23 May 2005 22:50:26 +0000 (15:50 -0700)]
As a result of the split of the kobject-registration and the
corresponding hotplug event, the order of events for device_add() has
changed. This restores the old order, cause it confused some userspace
applications.
