The CIA FLAG interrupt executes amiga_interrupt() which then calls
parport_generic_irq().
The call to parport_generic_irq() can be commented out and the printer
still prints exactly the same as with the call, dropping about every 2nd
char.
The interrupt is not doing anything, parport_ieee1284_write_compat() is
sending out bytes irrspective of interrupts.
