[PATCH] libata: fix non-uniform ports handling
Non-uniform ports handling got broken while updating libata to handle those in the same host. Only separate irq for the non-uniform secondary port was implemented while all other fields (host flags, transfer mode...) of the secondary port simply shared those of the first. For ata_piix combined mode, which ATM is the only user of non-uniform ports, this causes the secondary port assume the wrong type. This can cause PATA port to use SATA ops, which results in bogus check on PCS and detection failure. This patch adds ata_probe_ent->pinfo2 which points to optional port_info for the secondary port. For the time being, this seems to be the simplest solution. This workaround will be removed together with ata_probe_ent itself after init model is updated to allow more flexibility.
