Smatch complains that "wcidx" value comes from the network and thus
cannot be trusted. In this case, it actually seems to come from the
firmware. If your wireless firmware is malicious then probably no
amount of carefulness can protect you.
On the other hand, these days we still try to check the firmware as much
as possible. Verifying that the index is within bounds will silence a
static checker warning. And it's harmless and a good exercise in kernel
hardening. So I suggest that we do add a bounds check.

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.
