Subject: [ 13/58] workqueue: un-GPL function delayed_work_timer_fn()

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

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

From: Konstantin Khlebnikov <khlebnikov@...nvz.org>

commit 1438ade5670b56d5386c220e1ad4b5a824a1e585 upstream.

commit d8e794dfd51c368ed3f686b7f4172830b60ae47b ("workqueue: set
delayed_work->timer function on initialization") exports function
delayed_work_timer_fn() only for GPL modules. This makes delayed-works
unusable for non-GPL modules, because initialization macro now requires
GPL symbol. For example schedule_delayed_work() available for non-GPL.
