    tty/serial: kill off set_irq_flags usage · 2a446241
    Rob Herring authored
    set_irq_flags is ARM specific with custom flags which have genirq
    equivalents. Convert drivers to use the genirq interfaces directly, so we
    can kill off set_irq_flags. The translation of flags is as follows:
    
    IRQF_VALID -> !IRQ_NOREQUEST
    IRQF_PROBE -> !IRQ_NOPROBE
    IRQF_NOAUTOEN -> IRQ_NOAUTOEN
    
    For IRQs managed by an irqdomain, the irqdomain core code handles clearing
    and setting IRQ_NOREQUEST already, so there is no need to do this in
    .map() functions and we can simply remove the set_irq_flags calls. Some
    users also set IRQ_NOPROBE and this has been maintained although it is not
    clear that is really needed. There appears to be a great deal of blind
    copy and paste of this code.
