From 96c860fcf42bab4d599b601af05ea88bd1098e19 Mon Sep 17 00:00:00 2001 From: Lina Iyer Date: Tue, 30 Jun 2020 13:13:08 -0600 Subject: [PATCH] FROMLIST: cpuidle: governor: export cpuidle governor functions Commit 83788c0caed3 ("cpuidle: remove unused exports") removed capability of registering cpuidle governors, which was unused at that time. By exporting the symbol, let's allow platform specific modules to register cpuidle governors and use cpuidle_governor_latency_req() to get the QoS for the CPU.
