Merge branch 'for-4.1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

Pull libata fixes from Tejun Heo:
 "Rather big for fixes pull.

   - SCC controllers never lived to see the light of the day.  Both
     libata and ide drivers removed.

   - In some configurations, link power management policy changes
     sometimes cause delayed spurious PHY events which can develop into
     noticeable failures.  This has been reported several times over the
     years.  Gabriele's patches suppress PHY events for a while after
     LPM policy changes which should help most of these failures without
     causing too much problem for hotplug use cases.

   - A few controller specific fixes"

[ Hmm.  I don't think removing SSC support is really a "fix", but hey, it
  removes a lot of lines of code.  Which I like.  So ...  good riddance ]

* 'for-4.1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
  ahci: avoton port-disable reset-quirk
  ata: select DW_DMAC in case of SATA_DWC
  libata: Blacklist queued TRIM on all Samsung 800-series
  libata: Ignore spurious PHY event on LPM policy change
  libata: Add helper to determine when PHY events should be ignored
  ata: ahci_st: fixup layering violations / drvdata errors
  Remove celleb-only SCC PATA drivers
