From c65be1a63f1df224c8f22d72b9ec824241ada585 Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Mon, 25 Jun 2018 13:20:58 +0200 Subject: scsi: core: check for equality of result byte values When evaluating a SCSI command's result using the field access macros, check for equality of the fields and not if a specific bit is set. This is a preparation patch, for reworking the results field in the SCSI command.
