[PATCH 1/2] genirq: Set IRQCHIP_SKIP_SET_WAKE flag for dummy_irq_chip

From: Ingo Molnar
Date: Tue May 05 2015 - 12:24:22 EST


From: Roger Quadros <rogerq@xxxxxx>

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)
