Pull libata fixes from Tejun Heo: - Revert of sata_mv devm_ioremap_resource() conversion. It made init fail if there are overlapping resources which led to detection failures on some setups. - A workaround for an Acer laptop which sometimes reports corrupt port map. - Other non-critical fixes. * 'for-4.12-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: libata: fix error checking in in ata_parse_force_one() Revert "ata: sata_mv: Convert to devm_ioremap_resource()" ata: libahci: properly propagate return value of platform_get_irq() ata: sata_rcar: Handle return value of clk_prepare_enable ahci: Acer SA5-271 SSD Not Detected Fix
