| Subject: SCSI: mpt2sas: fix firmware failure with wrong task attribute |
| |
| From: Sreekanth Reddy <Sreekanth.Reddy@lsi.com> |
| |
| commit 48ba2efc382f94fae16ca8ca011e5961a81ad1ea upstream. |
| |
| When SCSI command is received with task attribute not set, set it to SIMPLE. |
| Previously it is set to untagged. This causes the firmware to fail the commands. |
