Subject: drm/amd/powerplay/vega10: allow mclk switching with no displays
From: Alex Deucher <[email protected]>
commit 5825acf5c958a6820b04e9811caeb2f5e572bcd8 upstream.
If there are no displays attached, there is no reason to disable mclk switching.
Fixes mclks getting set to high when there are no displays attached.
