NAME
       ata_host_alloc_pinfo - alloc host and init with port_info array

SYNOPSIS
       struct ata_host * ata_host_alloc_pinfo(struct device * dev,
                                              const struct ata_port_info *const * ppi,
                                              int n_ports);

ARGUMENTS
       dev
           generic device this host is associated with

       ppi
           array of ATA port_info to initialize host with

       n_ports
           number of ATA ports attached to this host
