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

From: Greg Kroah-Hartman
Date: Wed Dec 07 2016 - 02:08:58 EST


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

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

From: Hannes Reinecke <hare@xxxxxxx>

commit e0029dcb5b6e1c23e68f578ce7a3d6c5caba0501 upstream.

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