[ Upstream commit0d846bdc11] There's at least one case in ieee80211_rx_for_interface() where we might pass &((struct sta_info *)NULL)->sta to it only to then do container_of(), and then checking the result for NULL, but checking the result of container_of() for NULL looks really odd. Fix this by just passing the struct sta_info * instead.

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.
