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

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?

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?

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

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