In many cases the actual private data is very useful and constant for a given host controller so being able to just pass it at probe time would be very useful indeed (eg with the via driver would could pass the udma clocking and reduce the code size, or with the AMD one the UDMA multiplier and the offset) Signed-off-by: Alan Cox Signed-off-by: Jeff Garzik --- diff --git a/drivers/scsi/libata-core.c b/drivers/scsi/libata-core.c index a74b4071a6..e51d9a8a27 100644 --- a/drivers/scsi/libata-core.c +++ b/drivers/scsi/libata-core.c @@ -4563,6 +4563,7 @@ ata_pci_init_native_mode(struct pci_dev *pdev, struct ata_port_info **port, int probe_ent->irq = pdev->irq; probe_ent->irq_flags = SA_SHIRQ; + probe_ent->private_data = port[0]->private_data; if (ports & ATA_PORT_PRIMARY) { probe_ent->port[p].cmd_addr = pci_resource_start(pdev, 0); @@ -4599,6 +4600,7 @@ static struct ata_probe_ent *ata_pci_init_legacy_port(struct pci_dev *pdev, stru probe_ent->legacy_mode = 1; probe_ent->n_ports = 1; probe_ent->hard_port_no = port_num; + probe_ent->private_data = port->private_data; switch(port_num) { diff --git a/include/linux/libata.h b/include/linux/libata.h index a5390313c7..1464a7586d 100644 --- a/include/linux/libata.h +++ b/include/linux/libata.h @@ -405,6 +405,7 @@ struct ata_port_info { unsigned long mwdma_mask; unsigned long udma_mask; const struct ata_port_operations *port_ops; + void *private_data; }; struct ata_timing {
