ARM: S3C24XX: use samsung_sync_wakemask in s3c2412 pm
From: Heiko Stuebner <heiko@...> Date: Sat, 9 Feb 2013 13:30:32 +0100
Commit-Message
Originally the s3c2412 used a overidden irq chip to set the rtc wakeup flag. But with using the samsung_sync_wakemask function the same can be achieved without introducing soc specific irq functions. Signed-off-by: Heiko Stuebner <heiko@...>
