From 5e6acd1c8c4dc9a7c16208aeac3de09151ee6233 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Mon, 4 Apr 2016 11:43:56 +0200 Subject: [PATCH] libata-scsi: sanitize ata_gen_ata_sense() ata_to_sense_error() is called conditionally, so we should be generating a default sense if the condition is not met.
