Subject: genirq: Set IRQCHIP_SKIP_SET_WAKE flag for dummy_irq_chip
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=10a50f1ab5f06c9a;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

genirq: Set IRQCHIP_SKIP_SET_WAKE flag for dummy_irq_chip

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)
