Pull libata fixes from Tejun Heo:
 "Nothing too interesting.

  Arnd's gcc-7 warning fixes that slipped through the cracks for two
  release cycles (my bad), and two minor low level driver updates"

* 'for-4.14-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
  ahci: don't ignore result code of ahci_reset_controller()
  ata_piix: Add Fujitsu-Siemens Lifebook S6120 to short cable IDs
  ata: avoid gcc-7 warning in ata_timing_quantize
