NAME

6       ata_host_alloc - allocate and init basic ATA host resources
7

SYNOPSIS

9       struct ata_host * ata_host_alloc(struct device * dev, int max_ports);
10

ARGUMENTS

12       dev
13           generic device this host is associated with
14
15       max_ports
16           maximum number of ATA ports associated with this host
17

DESCRIPTION

19       Allocate and initialize basic ATA host resources. LLD calls this
20       function to allocate a host, initializes it fully and attaches it using
21       ata_host_register.
22
23       max_ports ports are allocated and host->n_ports is initialized to
24       max_ports. The caller is allowed to decrease host->n_ports before
25       calling ata_host_register. The unused ports will be automatically freed
26       on registration.

RETURNS

29       Allocate ATA host on success, NULL on failure.
