Is it necessary to hard-code an hand calculated size of the literal
strings? Can't we let the compiler do that for us? With this as type:

    static const char *cpufreq_policy_str[] = {

The compiler might not detect an issue if we write "11" instead of "12",
for example.

Otherwise the tool side of the patch looks fine to me,
so: Acked-by: Anthony PERARD <anthony.perard@vates.tech>
