From a436ae9434ec491eefb4ed4c77bdb9c762925976 Mon Sep 17 00:00:00 2001 From: Liao Chang Date: Wed, 16 Aug 2023 01:58:53 +0000 Subject: cpufreq: Use clamp() helper macro to improve the code readability The valid values of policy.{min, max} should be between 'min' and 'max', so use clamp() helper macro to makes cpufreq_verify_within_limits() easier to follow.
