Subject: drm/radeon: set si_notify_smc_display_change properly
From: Alex Deucher <alexander.deucher@xxxxxxx>
commit ffcda352b569dcf5be5c8a5f57545794acf4adb9 upstream.
This is effectively a revert of 4573388c92ee60b4ed72b8d95b73df861189988c.
Forcing a display active when there is none causes problems with
dpm on some SI boards which results in improperly initialized
dpm state and boot failures on some boards. As for the bug commit
4573388c92ee tried to address, one can manually force the state to
high for better performance when using the card as a headless compute
node until a better fix is developed.
