      libata: honour host controllers that want just one host · dc87c398

      The Marvell IDE interface on my machine would hit a BUG_ON() in
      lib/iomem.c because it was calling ata_pci_init_one() specifying just a
      single port on the host, but that would actually end up trying to
      initialize two ports, the second one with bogus information.
      
      This fixes "ata_pci_init_one()" so that it actually passes down the
      n_ports variable that it got from the low-level driver to the host
      allocation routine ("ata_host_alloc_pinfo()"), which results in the ATA
      layer actually having the correct port number information.
      
      And in order to make it all work, I also needed to fix a few places that
      had incorrectly hard-coded the fact that a host always had exactly two
      ports (both ata_pci_init_bmdma() and ata_request_legacy_irqs() would
      just always iterate over both ports).
