The structure *_irq_driver is passed as a parameter in sysdev_driver_register(). This in turn would add this structure to a list which may be traversed later.
Hence, even though the functions referenced through this structure have __init attribute, we cannot possibly add __initdata attribute to it.
To remove compilation warnings, the functions referenced thorugh this structure are also defined without __init attribute.
It removes following two warnings.
WARNING: vmlinux.o(.data+0x4f58): Section mismatch in reference from the variable s3c2416_irq_driver to the function .init.text:s3c2416_irq_add() The variable s3c2416_irq_driver references the function __init s3c2416_irq_add()
WARNING: vmlinux.o(.data+0x7c50): Section mismatch in reference from the variable s3c2443_irq_driver to the function .init.text:s3c2443_irq_add() The variable s3c2443_irq_driver references the function __init s3c2443_irq_add()
