[PATCH v2] genirq: Set IRQCHIP_SKIP_SET_WAKE flag for dummy_irq_chip

From: Roger Quadros
Date: Wed Apr 15 2015 - 04:14:41 EST


Without this system suspend is broken on systems that have
drivers calling enable/disable_irq_wake() for interrupts based off
the dummy irq hook.
(e.g. drivers/gpio/gpio-pcf857x.c)
