Subject: [PATCH AUTOSEL 6.6 10/18] drm/amd/display: Reset freesync config before update new state
From: Tom Chung <chiahsuan.chung@....com>
[ 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.
