[ Upstream commit e0b5127fa134fe0284d58877b6b3133939c8b3ce ] In ssb_calc_clock_rate(), there is a potential issue where the value of m1 could be zero due to initialization using clkfactor_f6_resolv(). This situation raised concerns about the possibility of a division by zero error. We fixed it by following the suggestions provided by Larry Finger <Larry.Finger@lwfinger.net> and Michael Büsch <m@bues.ch>. The fix involves returning a value of 1 instead of 0 in clkfactor_f6_resolv(). This modification ensures the proper functioning of the code and eliminates the risk of division by zero errors.

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.
