[PATCH v2] irqchip: exynos-combiner: Fix compilation error on ARM64

From: Naveen Krishna Chatradhi
Date: Wed Sep 03 2014 - 01:36:43 EST

The following compilation error occurs on 64-bit Exynos7 SoC:

drivers/irqchip/exynos-combiner.c: In function âcombiner_irq_domain_mapâ:
drivers/irqchip/exynos-combiner.c:162:2: error: implicit declaration of function âset_irq_flagsâ [-Werror=implicit-function-declaration]
set_irq_flags(irq, IRQF_VALID | IRQF_PROBE);
drivers/irqchip/exynos-combiner.c:162:21: error: âIRQF_VALIDâ undeclared (first use in this function)
set_irq_flags(irq, IRQF_VALID | IRQF_PROBE);
drivers/irqchip/exynos-combiner.c:162:21: note: each undeclared identifier is reported only once for each function it appears in
drivers/irqchip/exynos-combiner.c:162:34: error: âIRQF_PROBEâ undeclared (first use in this function)
set_irq_flags(irq, IRQF_VALID | IRQF_PROBE);

Fix the build error by including linux/interrupt.h.

Changes since v1:
Used linux/interrupt.h instead of asm/hardirq.h
