cpufreq: Documentation: Update description of rate_limit_us default value
Due to commit 37c6dccd6837 ("cpufreq: Remove LATENCY_MULTIPLIER")
updating the acquisition logic of cpufreq_policy_transition_delay_us(),
the original description of 2 ms has become inaccurate.
Therefore, update the description of the default value for
rate_limit_us from 2ms to 1ms.

The purpose of this tunable is to reduce the scheduler context overhead of the governor which might be excessive without it. |
