From 1bd5b715a305f6f13455e89becbd839010dd14b5 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 25 Mar 2008 12:22:49 +0900 Subject: libata: make ata_pci_init_one() not use ops->irq_handler and pi->sht ata_pci_init_one() is the only function which uses ops->irq_handler and pi->sht. Other initialization functions take the same information as arguments. This causes confusion and duplicate unused entries in structures. Make ata_pci_init_one() take sht as an argument and use ata_interrupt implicitly. All current users use ata_interrupt and if different irq handler is necessary open coding ata_pci_init_one() using ata_prepare_sff_host() and ata_activate_sff_host can be done under ten lines including error handling and driver which requires custom interrupt handler is likely to require custom initialization anyway. As ata_pci_init_one() was the last user of ops->irq_handler, this patch also kills the field.
