Pull ata fixes from Damien Le Moal:
 "Several minor fixes:

   - Fix the module alias for the ahci_imx driver to get autoloading to
     work (Alexander)

   - Fix a potential array-index-out-of-bounds problem with the
     enclosure managment support in the ahci driver (Kai-Heng)

   - Several patches to fix compilation warnings thrown by clang in the
     ahci_st, sata_rcar, ahci_brcm, ahci_xgene, ahci_imx and ahci_qoriq
     drivers (me)"
