I'm fine with either and that was my first thought here, too, but it did seem like
the comment was mostly placed there to justify the 'unexpected' high utilization
when explicitly passing FREQUENCY_UTIL and the need to clamp it then.
So removing did feel slightly more natural to me anyway.

Subject: [PATCH] sched/fair: Remove stale FREQUENCY_UTIL mention

effective_cpu_util() flags were removed, so remove mentioning of the
flag.

commit 9c0b4bb7f6 ("sched/cpufreq: Rework schedutil governor performance estimation")
reworked effective_cpu_util() removing enum cpu_util_type. Modify the
comment accordingly.
