Subject: [PATCH v3 4/6] irqchip: s3c24xx: use irq_create_mapping for parent irqs

From: [email-masked] (Heiko Stübner)
Date: Sun, 17 Mar 2013 14:07:17 +0100

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.
