[ Upstream commit 6b8487cdf9fc7bae707519ac5b5daeca18d1e85b ]
[Why] Sometimes the new_crtc_state->vrr_infopacket did not sync up with the current state. It will affect the update_freesync_state_on_stream() does not update the state correctly.
[How] Reset the freesync config before get_freesync_config_for_crtc() to make sure we have the correct new_crtc_state for VRR.
Please drop this patch from the stable queue entirely, since it has already been reverted (as of commit dc1000bf463d ("Revert "drm/amd/display: Reset freesync config before update new state"")).
