Faults are seen with RIP of lpfc_scsi_cmd_iocb_cmpl(). The failure is when lpfc_update_status is being called as part of the completion. After debugging, it was seen the issue was the shost pointer that the driver derived from the scsi cmd. The crash showed the cmd->device pointer being bogus, which is likely as the scsi devices were offlined prior. The bogus device pointer caused subsequent pointers derived from the location, specifically the vport, to be bogus. Fix by adjusting the calling sequence to pass in the vport rather than having to derive it from the cmd structure.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
