    Subject[PATCH v4 15/24] PM / devfreq: tegra30: Fix integer overflow on CPU's freq max out
    Date
    There is another kHz-conversion bug in the code, resulting in integer
    overflow. Although, this time the resulting value is 4294966296 and it's
    close to ULONG_MAX, which is okay in this case.
