- * ahci_host_activate - start AHCI host, request IRQs and register it
- * @host: target ATA host
- * @irq: base IRQ number to request
- * @sht: scsi_host_template to use when registering the host
- *
- * Similar to ata_host_activate, but requests IRQs according to AHCI-1.1
- * when multiple MSIs were allocated. That is one MSI per port, starting
- * from @irq.
- *
- * LOCKING:
- * Inherited from calling layer (may sleep).
- *
- * RETURNS:
- * 0 on success, -errno otherwise.
