Subject: [PATCH] Driver core: unregister_node() for hotplug use
Date: Mon, 20 Jun 2005 15:59:27 -0700 [thread overview]
Message-ID: <1119308367735@kroah.com> (raw)
In-Reply-To: <11193083671865@kroah.com>
[PATCH] Driver core: unregister_node() for hotplug use
This adds a generic function 'unregister_node()'.
It is used to remove objects of a node going away
for hotplug. All the devices on the node must be
unregistered before calling this function.
