[PATCH] libata: move ata_irq_on() into libata-sff.c
ata_irq_on() isn't used outside of libata core layer. The function is TF/SFF interface specific but currently used by core path with some hack too. Move it from include/linux/libata.h to drivers/ata/libata-sff.c. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
