Subject: [PATCH 4.8 01/35] libata-scsi: Fixup ata_gen_passthru_sense()

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hannes Reinecke <hare@...e.de>

commit e0029dcb5b6e1c23e68f578ce7a3d6c5caba0501 upstream.

There's a typo in ata_gen_passthru_sense(), where the first byte
would be overwritten incorrectly later on.
