| Subject: NOUPSTREAM: ANDROID: 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. |

| [CPNOTE: 20/05/21] Lee: This was rejected by Rafael, as there are no Mainline users |
| [CPNOTE: 26/05/21] Lee: Requested clarification from Todd |
| [CPNOTE: 08/09/21] Lee: Converting to ANDROID: |
