Subject: [PATCH v3 4/6] irqchip: s3c24xx: use irq_create_mapping for parent irqs
Date: Sun, 17 Mar 2013 14:07:17 +0100	[thread overview]
Message-ID: <201303171407.17660.heiko@sntech.de> (raw)
In-Reply-To: <201303171404.06146.heiko@sntech.de>

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.
