Subject[PATCH v2] irqchip: exynos-combiner: remove hard-coded irq_base value
Date
Replace irq_domain_add_simple with "irq_domain_add_linear" in order to use
linear irq domain, and to remove hardcoded irq_base_value.

Signed-off-by: Chander Kashyap <chander.kashyap@linaro.org>

Changes since v1:
- Replaced irq_domain_add_simple with irq_domain_add_linear,
as suggested by Tomasz
