From ced202f7bd78eb6a79c441a8b217e0f3d38bccfc Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Tue, 27 Apr 2021 10:30:12 +0200 Subject: scsi: core: Stop using DRIVER_ERROR Return the actual error code in __scsi_execute() (which, according to the documentation, should have happened anyway). And audit all callers to cope with negative return values from __scsi_execute() and friends.
