When an item of struct tipc_subscription is created, we fail to
initialize the two lists aggregated into the struct. This has so far
never been a problem, since the items are just added to a root
object by list_add(), which does not require the addee list to be
pre-initialized. However, syzbot is provoking situations where this
addition fails, whereupon the attempted removal if the item from
the list causes a crash.
This problem seems to always have been around, despite that the code
for creating this object was rewritten in commit 242e82cc95f6 ("tipc:
collapse subscription creation functions"), which is still in net-next.
We fix this for that commit by initializing the two lists properly.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
