link2, dev2.x are not leaking. pata_legacy.1 is not freed because of ata2.
I extracted some of the output where the ata port object is not freed properly:

Trying to match the put and get, I notice that scsi_add_host_with_dma
does 2 direct get, but scsi_remove_host only one direct put.
I did the following match:
ref=1++ (attribute_container_add_device:transport_setup_device:ata_tport_add)
--> ref=3-- (attribute_container_release:device_release:kobject_cleanup)
ref=3++ (klist_node_init:klist_add_tail:device_add) --> ref=4--
(klist_put:klist_del:device_del)
ref=3++ (attribute_container_add_class_device:transport_add_class_device:attribute_container_device_trigger)
--> ref=5--

ref=4++ (kobject_add:get_device_parent:device_add) --> ref=6--

ref=5++ (ata_tlink_add:ata_tport_add:ata_host_register) --> ref=7--

ref=6++ (ata_tlink_add:ata_tport_add:ata_host_register) --> ref=8--
(ata_tlink_delete:ata_tport_delete:ata_host_detach)
ref=7++ (kobject_add:device_add:ata_tlink_add) --> ref=9--
(device_del:ata_tlink_delete:ata_tport_delete)
ref=8++ (scsi_add_host_with_dma:ata_scsi_add_hosts:ata_host_register)
--> ref=10-- (scsi_remove_host:ata_host_detach:..
ref=9++ (kobject_add:device_add:scsi_add_host_with_dma) -->
ref=11-- (device_del:scsi_remove_host:ata_host_detach)
ref=10++ (scsi_add_host_with_dma:ata_scsi_add_hosts:ata_host_register)
Then the final call should have trigger destruction the port object:
ref=2-- (ata_tport_delete:ata_host_detach:legacy_init [pata_legacy])
Looking at scsi_add_host_with_dma/scsi_remove_host, we need to do
get_device on shost->shost_gendev.parent because we will do put_device
in scsi_host_dev_release, the release function of shost_gendev (which
is not called).
We do get_device on shost->shost_gendev for scsi_host_cls_release()
put_device, the release function of shost->host_dev, so I think it is
fine.
I am wondering if we don't have a circular dependency:
We do the final put_device (in scsi_host_put) on ap->scsi_host in
ata_host_release(), but it is not called because
[scsi_host]->shost_gendev.parent is &ap->tdev which hold the put on
its parent, ap.
If my understanding is correct, as Tejun pointed out, removing the put
on ap in ata_tport_release and the get_device(parent) in ata_tport_add
should unlock the situation.
