Hi Abhilash,
Just two minor issues inline. I leave them up to Linus to decide.
Linus, if you don't mind them, feel free to apply this patch with my Ack.

Quite an awful name for a local variable. "irq_chip" alone would be enough.

sizeof(*exynos_wkup_irq_chip) (or irq_chip considering my comment above)
could be used instead.
