From b48cd0d12f8e3b5fc928ac84734e563eda8e430f Mon Sep 17 00:00:00 2001 From: Yury Norov Date: Sun, 23 Jan 2022 10:38:47 -0800 Subject: cpufreq: replace cpumask_weight with cpumask_empty where appropriate drivers/cpufreq calls cpumask_weight() to check if any bit of a given cpumask is set. We can do it more efficiently with cpumask_empty() because cpumask_empty() stops traversing the cpumask as soon as it finds first set bit, while cpumask_weight() counts all bits unconditionally.
