+Subject: scsi: aacraid: Correct hba_send to include iu_type
+
+From: Dave Carroll <david.carroll@microsemi.com>
+
+commit 7d3af7d96af7b9f51e1ef67b6f4725f545737da2 upstream.
+
+commit b60710ec7d7a ("scsi: aacraid: enable sending of TMFs from
+aac_hba_send()") allows aac_hba_send() to send scsi commands, and TMF
+requests, but the existing code only updates the iu_type for scsi
+commands. For TMF requests we are sending an unknown iu_type to
+firmware, which causes a fault.
+
+Include iu_type prior to determining the validity of the command
+

+Fixes: b60710ec7d7ab ("aacraid: enable sending of TMFs from aac_hba_send()")
+Fixes: 423400e64d377 ("aacraid: Include HBA direct interface")
