- *	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.
