From: Deepak Sikri <redacted> enable_irq_wake() has a callback for interrupt controllers. But since gic handler did not had this call back associated, it was always returning -ENXIO, which was breaking the existing drivers. This patch adds dummy handlers in gic in order to avoid breaking of existing drivers.
