commit0f5cb0e622upstream. Commita982e45dc1("clk: at91: PLL recalc_rate() now using cached MUL and DIV values") removed a check that prevents a division by zero. This now causes a stacktrace when booting the kernel on a at91 platform if the PLL DIV register contains zero. This commit reintroduces this check.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
