To: Greg KH <gregkh@linuxfoundation.org>
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Subject: enclosure: convert class code to use dev_groups
The dev_attrs field of struct class is going away soon, dev_groups
should be used instead. This converts the enclosure class code to use
the correct field.
