iscsi_create_conn() exposed iscsi_cls_conn to sysfs prior to initialization of iscsi_conn's dd_data. When userspace tried to access an attribute such as the connect address, a NULL pointer dereference was observed. Do not add iscsi_cls_conn to sysfs until it has been initialized. Remove iscsi_create_conn() since it is no longer used.

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.
