From 6d32d30f55020d766388df7515f771f68c973033 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Wed, 15 Aug 2007 05:38:46 -0400 Subject: [libata] Remove ->irq_ack() hook, and ata_dummy_irq_on() * ->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() Signed-off-by: Jeff Garzik --- include/linux/libata.h | 4 ---- 1 file changed, 4 deletions(-) (limited to 'include') diff --git a/include/linux/libata.h b/include/linux/libata.h index b89d191ceb2..9295cd541ff 100644 --- a/include/linux/libata.h +++ b/include/linux/libata.h @@ -644,7 +644,6 @@ struct ata_port_operations { irq_handler_t irq_handler; void (*irq_clear) (struct ata_port *); u8 (*irq_on) (struct ata_port *); - u8 (*irq_ack) (struct ata_port *ap, unsigned int chk_drq); int (*scr_read) (struct ata_port *ap, unsigned int sc_reg, u32 *val); int (*scr_write) (struct ata_port *ap, unsigned int sc_reg, u32 val); @@ -852,9 +851,6 @@ extern int ata_scsi_change_queue_depth(struct scsi_device *sdev, extern struct ata_device *ata_dev_pair(struct ata_device *adev); extern int ata_do_set_mode(struct ata_link *link, struct ata_device **r_failed_dev); extern u8 ata_irq_on(struct ata_port *ap); -extern u8 ata_dummy_irq_on(struct ata_port *ap); -extern u8 ata_irq_ack(struct ata_port *ap, unsigned int chk_drq); -extern u8 ata_dummy_irq_ack(struct ata_port *ap, unsigned int chk_drq); extern int ata_cable_40wire(struct ata_port *ap); extern int ata_cable_80wire(struct ata_port *ap); -- cgit v1.2.3
