Subject: [PATCH] scsi: hpsa: fix the device_id in hpsa_update_device_info()
Date: Thu, 17 Aug 2017 17:44:44 +0300 [thread overview]
Message-ID: <20170817144444.tocisnlw6grmaf75@mwanda> (raw)
The parentheses are in the wrong place so we specify the length as
"sizeof(this_device->device_id) < 0" which is zero.
Fixes: 988b87edd231 ("scsi: hpsa: Ignore errors for unsupported LV_DEVICE_ID VPD page")
