irqchip: s3c24xx: use irq_create_mapping for parent irqs
From: Heiko Stuebner <heiko@...> Date: Sat, 16 Mar 2013 15:35:30 +0100
Commit-Message
Getting the parent irq number thru irq_find_mapping will fail for non-legacy irq_domains, as the mapping of the parent irq won't have been created. As irq_create_mapping will just output an already mapped irq number if its already mapped, this does also not influence the legacy mappings. Signed-off-by: Heiko Stuebner <heiko@...>
