From 8d5f8a4f25b1cb88e5a75e83e223e1197f9d734d Mon Sep 17 00:00:00 2001 From: Riwen Lu Date: Tue, 23 Aug 2022 15:43:42 +0800 Subject: [PATCH] ACPI: processor: Remove freq Qos request for all CPUs commit 36527b9d882362567ceb4eea8666813280f30e6f upstream. The freq Qos request would be removed repeatedly if the cpufreq policy relates to more than one CPU. Then, it would cause the "called for unknown object" warning. Remove the freq Qos request for each CPU relates to the cpufreq policy, instead of removing repeatedly for the last CPU of it.
