Ask help about killing irqchip.irq_print_chip on PPC platforms

[Jiang Liu]

Hi Scott and Tudor,
	Sorry, resend and Ccing the list.
	We are trying to clean up some irqchip interfaces, and
irqchip.irq_print_chip is a candidate for removal. After some
changes on x86 side, arch/powerpc/sysdev/fsl_msi.c may be the
last user of irqchip.irq_print_chip. So could you please help
to advice on whether we could kill irqchip.irq_print_chip
by using "fsl-msi" instead of "fsl-msi-%d" for irqchip name?
Will it break any userspace interfaces?
Thanks!
Gerry
