Clear Kernel Build Error? Fix It

when I compile Clear kernel with LLVM enabled, I got this error:

  arch/x86/kernel/cpu/intel_epb.c:172:2: error: call to undeclared function 'sched_set_itmt_power_ratio';
  ISO C99 and later do not support implicit function declarations [-Werror,-Wimplicit-function-declaration]
          sched_set_itmt_power_ratio(256 - val * 2, cpu);
          ^
  arch/x86/kernel/cpu/intel_epb.c:172:2: note: did you mean 'sched_set_itmt_core_prio'?

  static inline void sched_set_itmt_core_prio(int prio, int core_cpu)
                     ^
  1 error generated.

it's obvious that the sched_set_itmt_power_ratio function is undeclared so I added the following like the function on top of it and it is able to compile :)
