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

Pull libata fixes from Tejun Heo:
 "This is quite late but SCT Write Same support added during this cycle
  is broken subtly but seriously and it'd be best to disable it before
  v4.9 gets released.

  This contains two commits - one low impact sata_mv fix and the
  mentioned disabling of SCT Write Same"

* 'for-4.9-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
  libata-scsi: disable SCT Write Same for the moment
  ata: sata_mv: check for errors when parsing nr-ports from dt
