Merge tag 'tag/upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev

Pull libata fixes from Jeff Garzik:

1) Fix regression that could cause a misdiagnosis, which in turn could
   lead to an erroneous 3.0 Gbps -> 1.5 downshift, particularly when hotplug
   and suspend/resume is involved.

2) Fix a regression that led to ata%d controller ids being numbered one
   larger than in <= 3.4-rc3 (oh, the horror!).  Controller ids should now be
   as expected.

3) add some DT, PCI id's

4) ata/pata_arasan_cf: minor cpp fixing/cleaning

* tag 'tag/upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev:
  ata: ahci_platform: Add synopsys ahci controller in DT's compatible list
  ata/pata_arasan_cf: Move arasan_cf_pm_ops out of #ifdef, #endif macros
  libata: init ata_print_id to 0
  ahci: Detect Marvell 88SE9172 SATA controller
  libata: skip old error history when counting probe trials
