Current calculation for period and high_width may have 64-bit overflow. state->period and rate are u64. rate * state->period will overflow. clk_div = div_u64(rate * state->period, NSEC_PER_SEC) period = div64_u64(rate * state->period, div); high_width = div64_u64(rate * state->duty_cycle, div); This patch is to resolve it by using mul_u64_u64_div_u64().

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.
