    [libata] Remove ->irq_ack() hook, and ata_dummy_irq_on() · 6d32d30f
    Jeff Garzik authored
    * ->irq_ack() is redundant to what the irq handler already
      performs... chk-status + irq-clear.  Furthermore, it is only
      called in one place, when screaming-irq-debugging is enabled,
      so we don't want to bother with a hook just for that.
    * ata_dummy_irq_on() is only ever used in drivers that have
      no callpath reaching ->irq_on().  Remove .irq_on hook from
      those drivers, and the now-unused ata_dummy_irq_on()
