scsi: aacraid: Correct hba_send to include iu_type
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 Reported-by: Noah Misner <nmisner@us.ibm.com> Fixes: b60710ec7d7ab ("aacraid: enable sending of TMFs from aac_hba_send()") Fixes: 423400e64d377 ("aacraid: Include HBA direct interface") Tested-by: Noah Misner <nmisner@us.ibm.com> cc: stable@vger.kernel.org Signed-off-by: Dave Carroll <david.carroll@microsemi.com> Reviewed-by: Raghava Aditya Renukunta <RaghavaAditya.Renukunta@microsemi.com> Reviewed-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Martin K.
