    Subject[PATCH 16/21] powerpc: Add missing prototype for init_IRQ
    Date
    A function init_IRQ was added without a prototype declared in header irq.h.
    Fix the following warning (treated as error in W=1):

    CC arch/powerpc/kernel/irq.o
    arch/powerpc/kernel/irq.c:662:13: error: no previous prototype for ‘init_IRQ’ [-Werror=missing-prototypes]
    void __init init_IRQ(void)
    ^~~~~~~~
    cc1: all warnings being treated as errors
