Merge branch 'for-4.9-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata fixes from Tejun Heo:
"The recent changes in ahci MSI handling need one more fix. Hopefully,
this restores parity with before.
The other two are minor fixes with both low impact and risk"
* 'for-4.9-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
ahci: always fall back to single-MSI mode
libata-scsi: Fixup ata_gen_passthru_sense()
mvsas: fix error return code in mvs_task_prep()
