From 57eee3d23e8833ca18708b374c648235691942ba Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 12 Mar 2008 00:59:38 +0100 Subject: Driver core: Call device_pm_add() after bus_add_device() in device_add() Include dpm_sysfs_add() into device_pm_add(), in analogy with device_pm_remove(), and modify device_add() to call the latter after bus_add_device(), to avoid situations in which the PM core may attempt to suspend a device the registration of which has not been successful.
