[PATCH 10/17] ARM: s3c24xx: fix multiple section mismatch warnings

[Arnd Bergmann]

The *_irq_add function should not be marked __init because the driver
subsystem thinks they might be called at a later stage.

The usb_simtec_init function accesses initdata and should be marked
init. This is safe because the only caller is also an init function.

Without this patch, building s3c2410_defconfig results in:

WARNING: arch/arm/mach-s3c24xx/built-in.o(.data+0x1030): Section mismatch in reference from the variable s3c2416_irq_interface to the function .init.text:s3c2416_irq_add()
The variable s3c2416_irq_interface references
the function __init s3c2416_irq_add()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

WARNING: arch/arm/mach-s3c24xx/built-in.o(.data+0x1b08): Section mismatch in reference from the variable s3c2443_irq_interface to the function .init.text:s3c2443_irq_add()
The variable s3c2443_irq_interface references
the function __init s3c2443_irq_add()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

WARNING: arch/arm/mach-s3c24xx/built-in.o(.data+0xf44): Section mismatch in reference from the variable s3c2416_irq_interface to the function .init.text:s3c2416_irq_add()
The variable s3c2416_irq_interface references
the function __init s3c2416_irq_add()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

WARNING: arch/arm/mach-s3c24xx/built-in.o(.text+0x3f7c): Section mismatch in reference from the function usb_simtec_init() to the (unknown reference) .init.data:(unknown)
The function usb_simtec_init() references
the (unknown reference) __initdata (unknown).
This is often because usb_simtec_init lacks a __initdata
annotation or the annotation of (unknown) is wrong.
