Arun Easi 6a81533d61 scsi: qla2xxx: Fix kernel crash after disconnecting NVMe devices
BUG: unable to handle kernel NULL pointer dereference at           (null)
IP: [<ffffffffc050d10c>] qla_nvme_unregister_remote_port+0x6c/0xf0 [qla2xxx]
PGD 800000084cf41067 PUD 84d288067 PMD 0

RIP  [<ffffffffc050d10c>] qla_nvme_unregister_remote_port+0x6c/0xf0 [qla2xxx]

The crash is due to a bad entry in the nvme_rport_list. This list is not
protected, and when a remoteport_delete callback is called, driver
traverses the list and crashes.

Actually, the list could be removed and driver could traverse the main
fcport list instead. Fix does exactly that.

README

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.
