From 1971b18785d198ae5adbb861136ae5c0f195c14d Mon Sep 17 00:00:00 2001 From: Jie Zhan Date: Thu, 28 Aug 2025 19:02:11 +0800 Subject: [PATCH] cpufreq: CPPC: Don't warn if FIE init fails to read counters During the CPPC FIE initialization, reading perf counters on offline cpus should be expected to fail. Don't warn on this case. Also, change the error log level to debug since FIE is optional.
