irqchip: exynos-combiner: Fix compilation error on ARM64
The following compilation error occurs on 64-bit Exynos7 SoC:
drivers/irqchip/exynos-combiner.c: In function ‘combiner_irq_domain_map’:
drivers/irqchip/exynos-combiner.c:162:2: error: implicit declaration of function ‘set_irq_flags’ [-Werror=implicit-function-declaration]
set_irq_flags(irq, IRQF_VALID | IRQF_PROBE);
^
drivers/irqchip/exynos-combiner.c:162:21: error: ‘IRQF_VALID’ 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: ‘IRQF_PROBE’ undeclared (first use in this function)
set_irq_flags(irq, IRQF_VALID | IRQF_PROBE);
Fix the build error by including linux/interrupt.h.
