This function only checks if mbox_chan *chan is not NULL, but that cannot be the case and if it was returning NULL which is not later checked doesn't save us from this. The second check for chan->con_priv is completely redundant as if it was NULL we would return NULL just the same. Simply dereference con_priv directly and remove this function.

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.
