Hello nagalakshmi.nandigama@xxxxxxx,
This is a semi-automatic email about new static checker warnings.
The patch 921cd8024b90: "[SCSI] mpt2sas: New feature - Fast Load
Support" from Oct 19, 2011, leads to the following Smatch complaint:
drivers/scsi/mpt2sas/mpt2sas_base.c +3506 mpt2sas_port_enable_done()
error: we previously assumed 'mpi_reply' could be null (see line 3499)
drivers/scsi/mpt2sas/mpt2sas_base.c
3498 ioc->port_enable_cmds.status |= MPT2_CMD_COMPLETE;
3499 if (mpi_reply) {
^^^^^^^^^
check.
3500 ioc->port_enable_cmds.status |= MPT2_CMD_REPLY_VALID;
3501 memcpy(ioc->port_enable_cmds.reply, mpi_reply,
3502 mpi_reply->MsgLength*4);
3503 }
3504 ioc->port_enable_cmds.status &= ~MPT2_CMD_PENDING;
3505
3506 ioc_status = le16_to_cpu(mpi_reply->IOCStatus) & MPI2_IOCSTATUS_MASK;
^^^^^^^^^^^
dereference.
3507
3508 if (ioc_status != MPI2_IOCSTATUS_SUCCESS)
regards,
dan carpenter
