Merge branch 'for-4.2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata fixes from Tejun Heo: "A couple important fixes. - A block layer change which removed restriction on max transfer size led to silent data corruption on some devices. A new quirk is added to restore the old size limit for the reported device. If it gets reported on more devices, we might have to consider restoring the restriction for ATA devices by default. - There finally is a SSD which is confirmed to cause data corruption on TRIM regardless of which flavor is used. A new quirk is added and the device is blacklisted - Other device-specific workarounds" * 'for-4.2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: libata: Do not blacklist M510DC libata: increase the timeout when setting transfer mode libata: add ATA_HORKAGE_MAX_SEC_1024 to revert back to previous max_sectors limit libata: force disable trim for SuperSSpeed S238 libata: add ATA_HORKAGE_NOTRIM libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk for HP 250GB SATA disk VB0250EAVER ata: pmp: add quirk for Marvell 4140 SATA PMP
