[ Upstream commit78f6f40602] If the Si5341 is being initially programmed and has no stored NVM configuration, some of the register contents may contain unexpected values, such as zeros, which could cause divide by zero errors during driver initialization. Trap errors caused by zero registers or zero clock rates which could result in divide errors later in the code.

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.
