[PATCH V2 5/5] cpufreq: Force sync policy boost with global boost on sysfs update
From: Viresh Kumar
Date: Thu Apr 24 2025 - 12:22:34 EST
If the global boost flag is enabled and policy boost flag is disabled, a
call to `cpufreq_boost_trigger_state(true)` must enable the policy's
boost state.
The current code misses that because of an optimization. Fix it.
