cpufreq: arm_big_little: make function arguments and structure pointer const
Make the arguments of functions bL_cpufreq_{register/unregister} as const as the ops pointer does not modify the fields of the cpufreq_arm_bL_ops structure it points to. The pointer arm_bL_ops is also getting initialized with ops but the pointer does not modify the fields. So, make the function argument and the structure pointer const. Add const to function prototypes too. Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
