From 7e26e3ea028740f934477ec01ba586ab033c35aa Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Tue, 27 Apr 2021 10:30:11 +0200 Subject: scsi: scsi_dh_alua: Check for negative result value scsi_execute() will now return a negative error if there was an error prior to command submission; evaluate that instead if checking for DRIVER_ERROR.
