From a9d2d8065821feec2e061ee39988d2f4d27631ea Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Tue, 27 Apr 2021 10:30:34 +0200 Subject: scsi: acornscsi: Translate message byte to host byte Instead of setting the message byte translate it to the appropriate host byte. As error recovery would return DID_ERROR for any non-zero message byte the translation doesn't change the error handling. And use SCSI result accessors while we're at it.
