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!
