3.19.8-ckt4 -stable review patch.  If anyone has any objections, please let me know.

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

From: Nicolas Boichat <drinkcat at chromium.org>

commit 7ea3470a7277380248135a592a849e1c27960b2f upstream.

Prevents frequent panic on boot, if the irq handler rt5645_irq
gets called before the workqueue rt5645_jack_detect_work is
initialized.
