Merge branch 'for-4.13-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata 

Pull libata fixes from Tejun Heo:
 "Dan found a really old bug where libata hotplug code wasn't sanitizing
  index value from userland and may end up indexing with a negative
  number. It is scary but fortunately can only be triggered by root.

  Other than that, minor fixes"

* 'for-4.13-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
  libata: fix a couple of doc build warnings
  libata: array underflow in ata_find_dev()
  ata: sata_rcar: add gen[23] fallback compatibility strings
  libata: remove unused rc in ata_eh_handle_port_resume
  libata: Cleanup ata_read_log_page()
  ata: fix gemini Kconfig dependencies
