From foo@baz Mon Sep 9 14:31:30 PDT 2013
Date: Mon, 09 Sep 2013 14:31:30 -0700
To: Greg KH <gregkh@linuxfoundation.org>
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Subject: hv: move "monitor_id" bus attribute to dev_groups
This moves the "state" bus attribute to the dev_groups structure,
removing the need for it to be in a temporary structure.
