Hi Grant,

Let me resend again.
I haven't received your answer the following my question yet.

Let me clarify your saying.
  a) We shouldn't use request_irq( ) ?
  b) Does Your  "irq_chip_generic" mean irq_set_handler_data( ) /
irq_set_chained_handler( ) ?
      If yes, Using these functions, I saw IRQ shared other function's
interrupt becomes invalid.
