Merge branch 'for-4.9-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata 

Pull libata fixes from Tejun Heo:
 "The recent changes in ahci MSI handling need one more fix.  Hopefully,
  this restores parity with before.

  The other two are minor fixes with both low impact and risk"

* 'for-4.9-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
  ahci: always fall back to single-MSI mode
  libata-scsi: Fixup ata_gen_passthru_sense()
  mvsas: fix error return code in mvs_task_prep()
