Subject: [PATCH 3.16 098/294] irqchip: brcmstb-l2: Define an
 irq_pm_shutdown function

3.16.50-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Florian Fainelli <f.fainelli@...il.com>

commit c017d21147848fe017772764a77a7f32c5b017f9 upstream.

The Broadcom STB platforms support S5 and we allow specific hardware
wake-up events to take us out of this state. Because we were not
defining an irq_pm_shutdown() function pointer, we would not be
correctly masking non-wakeup events, which would result in spurious
wake-ups from sources that were not explicitly configured for wake-up.

Fixes: 7f646e92766e ("irqchip: brcmstb-l2: Add Broadcom Set Top Box Level-2 interrupt controller")
