- int ata_host_start(struct ata_host * host);
- ATA host to start ports for
Start and then freeze ports of host. Started status is recorded in host->flags, so this function can be called multiple times. Ports are guaranteed to get started only once. If host->ops isn't initialized yet, its set to the first non-dummy port ops.
Inherited from calling layer (may sleep).
0 if all ports are started successfully, -errno otherwise.
