[PATCH] irqchip/mmp: fix missing extern init code

[Ben Dooks]

The functions icu_init_irq and mmp2_init_icu are exported
from this code, so declare them in the header file to avoid
the following sparse warnings:

drivers/irqchip/irq-mmp.c:248:13: warning: symbol 'icu_init_irq' was not declared. Should it be static?
drivers/irqchip/irq-mmp.c:271:13: warning: symbol 'mmp2_init_icu' was not declared. Should it be static?

$ git grep -E "icu_init_irq|mmp2_init_icu"
arch/arm/mach-mmp/mmp2.c:       mmp2_init_icu();
arch/arm/mach-mmp/mmp2.h:extern void __init mmp2_init_icu(void);
arch/arm/mach-mmp/pxa168.c:     icu_init_irq();
arch/arm/mach-mmp/pxa168.h:extern void __init icu_init_irq(void);
arch/arm/mach-mmp/pxa910.c:     icu_init_irq();

If you are going to fix this, please fix it sensibly.

Thanks,

Ok, didn't realise these where not being built my the v7_multi defconfig.
Should this all go into one patch or do the arch/arm bits need to go via
some arm tree?

One single patch please, which I'll queue directly.
