Re: [PATCH 4/4] cpufreq: schedutil: Don't call sugov_get_util() unnecessarily

sugov_update_shared() may get called to clear the scheduling class flags
and we would return immediately in that case. Calling sugov_get_util()
in that case isn't going to be of any use then. Move invocation of
sugov_get_util() after the clear flag is checked.
