add_kallsyms() assigns the RCU pointer module::kallsyms and setups the structures behind it which point to init-data. The module was not published yet, nothing can see the kallsyms pointer and the data behind it. Also module's init function was not yet invoked. There is no need to use rcu_dereference() here, it is just to keep checkers quiet. The whole RCU read section is also not needed. Use a local kallsyms pointer and setup the data structures. Assign that pointer to the data structure at the end via rcu_assign_pointer().

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 reStructuredText 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.
