    libata: make sff_irq_on() method optional · e42a542b
    Sergei Shtylyov authored
    Now, with the introduction of the sff_set_devctl() method, we can
    use it in sff_irq_on() method too -- that way its implementations
    in 'pata_bf54x' and 'pata_scc' become virtually identical to
    ata_sff_irq_on().  The sff_irq_on() method now becomes quite
    superfluous, and the only reason not to remove it completely is
    the existence of the 'pata_octeon_cf' driver which implements it
    as an empty function. Just make the method optional then, with
    ata_sff_irq_on() becoming generic taskfile-bound function, still
    global for the 'pata_bf54x' driver to be able to call it from its
    thaw() and postreset() methods.
    
    While at it, make the sff_irq_on() method and ata_sff_irq_on() return
    'void' as the result is always ignored anyway.
