irqchip: s3c24xx: make interrupt handling independent of irq_domain structure
Keep a pointer to the corresponding s3c_irq_data struct as irq_chip_data. This removes the need to fetch the intc struct from the irq_domains host_data, thus making it independent of the underlying irq_domain structure. Also keep the real register offset of the interrupt in the s3c_irq_data struct to make it independent of the hwirq structure in the irq_domain Signed-off-by: Heiko Stuebner <heiko@sntech.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
