NAME
       ata_host_start - start and freeze ports of an ATA host

SYNOPSIS

ARGUMENTS
       host
           ATA host to start ports for

       host->ops isn't initialized yet, its set to the first non-dummy port ops.

       LOCKING: Inherited from calling layer (may sleep).

RETURN
       0 if all ports are started successfully, -errno otherwise.
