Due to a target port D_ID swap, it is possible for the lpfc_register_remote_port() routine to touch post mortem fc_rport memory when trying to access fc_rport->dd_data. The D_ID swap causes a simultaneous call to lpfc_unregister_remote_port(), where fc_remote_port_delete() reclaims fc_rport memory. Remove the fc_rport->dd_data->pnode NULL assignment because the following line reassigns ndlp->rport with an fc_rport object from fc_remote_port_add() anyways. The pnode nullification is superfluous.

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.
