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

From: Naveen Krishna Chatradhi
Date: Tue Sep 02 2014 - 11:29:41 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 asm/hardirq.h.
