ARM: S3C24XX: modify s3c2443 irq init to initialize all irqs
From: Heiko Stuebner <heiko@...> Date: Sat, 17 Nov 2012 18:02:21 +0100
Commit-Message
Previously the irq init used s3c24xx_init_irq and an additional arch_initcall to add the cpu specific irqs. To be able to simplyfy the irq init later, create a new function s3c2443_init_irq, which then calls s3c24xx_init_irq but also adds the cpu specific irqs. Signed-off-by: Heiko Stuebner <heiko@...>
