[PATCH 3/4] libata-sff.c: add another IRQ calls
From: Akira Iguchi <hidden>

linux-ide
When enabling IRQ, ap->ops->irq_on is checked. Because most drivers can use ata_irq_on() as is, this patch allows ap->ops->irq_on to be NULL. If it is NULL, ata_irq_on() are used. Signed-off-by: Kou Ishizaki <redacted> Signed-off-by: Akira Iguchi <redacted> ---
