Subject: [PATCH 3.15 09/84] workqueue: fix dev_set_uevent_suppress() imbalance

3.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Maxime Bizon <mbizon@...ebox.fr>

commit bddbceb688c6d0decaabc7884fede319d02f96c8 upstream.

Uevents are suppressed during attributes registration, but never
restored, so kobject_uevent() does nothing.
