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
