implicit declaration of function set_irq_chip_and_handler

implicit declaration of function set_irq_chip_and_handler

[Olaf Hering]

Current Linus tree has two new warnings

arch/powerpc/kernel/irq.c: In function irq_dispose_mapping:
arch/powerpc/kernel/irq.c:642: warning: implicit declaration of function set_irq_chip_and_handler
arch/powerpc/sysdev/mpic.c: In function mpic_host_map:
arch/powerpc/sysdev/mpic.c:770: warning: implicit declaration of function set_irq_chip_and_handler

It links anyway for some reason.
There is no prototype anymore, but still many users.

a460e745e8f9c75a0525ff94154a0629f9d3e05d is likely the culprit:
 [PATCH] genirq: clean up irq-flow-type naming

oops, that was unintended. The patch below should fix this.

From: Ingo Molnar <mingo@elte.hu>

re-add the set_irq_chip_and_handler() prototype, it's still widely used.
