commit8ea3819c0bupstream. The cordic routine for calculating sines and cosines that was added in commit6f98e62a9f("b43: update cordic code to match current specs") contains an error whereby a quantity declared u32 can in fact go negative. This problem was detected by Priit Laes who is switching b43 to use the routine in the library functions of the kernel.

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.
