From: Hannes Reinecke <hare@suse.de> stable inclusion from linux-4.19.198 commit f4bde1d1bf905590c55acb02104c60d1c281a24f -------------------------------- [ Upstream commit 7e26e3ea028740f934477ec01ba586ab033c35aa ] 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.
