bcsr_csc_handler() is a cascading interrupt handler. It has a disable_irq_nosync()/enable_irq() pair around the generic_handle_irq() call. The value of this disable/enable is zero because its a complete noop: disable_irq_nosync() merily increments the disable count without actually masking the interrupt. enable_irq() soleley decrements the disable count without touching the interrupt chip. The interrupt cannot arrive again because the complete call chain runs with interrupts disabled. Remove it.
