5ba207e55e scsi: mpi3mr: Fix error code in mpi3mr_transport_smp_handler()
The error code from mpi3mr_post_transport_req() is supposed to be passed to
bsg_job_done(job, rc, reslen), but it isn't.

a113c02f57 scsi: mpi3mr: Fix error codes in mpi3mr_report_manufacture()
There are three error paths which return success:

1) Propagate the error code from mpi3mr_post_transport_req() if it fails.

2) Return -EINVAL if "ioc_status != MPI3_IOCSTATUS_SUCCESS".

3) Return -EINVAL if "le16_to_cpu(mpi_reply.response_data_length) !=
   sizeof(struct rep_manu_reply)"

2745ce0e6d scsi: mpi3mr: Refresh SAS ports during soft reset
Update the host's SAS ports if there is change in port id or phys. If the
port id is changed, then the driver updates it. If some phys are
enabled/disabled during reset, then driver updates them in STL.

Check for the responding expander devices and update the device handle if
it got changed. Register the expander with STL if it got added during reset
and unregister the expander device if it got removed during reset.

[mkp: include fix for zeroday warning]
