Justin Tee 7bcba0a48c scsi: lpfc: Update PRLO handling in direct attached topology
[ Upstream commit 1f0f7679ad8942f810b0f19ee9cf098c3502d66a ]

A kref imbalance occurs when handling an unsolicited PRLO in direct
attached topology.

Rework PRLO rcv handling when in MAPPED state.  Save the state that we were
handling a PRLO by setting nlp_last_elscmd to ELS_CMD_PRLO.  Then in the
lpfc_cmpl_els_logo_acc() completion routine, manually restart discovery.
By issuing the PLOGI, which nlp_gets, before nlp_put at the end of the
lpfc_cmpl_els_logo_acc() routine, we are saving us from a final nlp_put.
And, we are still allowing the unreg_rpi to happen.

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.
