clk: visconti: prevent array overflow in visconti_clk_register_gates()
This code was using -1 to represent that there was no reset function. Unfortunately, the -1 was stored in u8 so the if (clks[i].rs_id >= 0) condition was always true. This lead to an out of bounds access in visconti_clk_register_gates().

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.
