From df79f020e59f55d6c2e14912b1f21375a342bdde Mon Sep 17 00:00:00 2001

Subject: [PATCH 0737/2940] drm/amd/display: Remove the check to see if
pp_display_cfg is changed
[Why]
When going to full-screen mode commit_planes_for_stream tries to decrease
dcf_deep_sleep value, but safe_to_lower is false, so we don't send the new value
to SMU but dc context gets updated.
Later when dc_post_update_surfaces_to_stream tries to lower dcf_ds when
safe_to_lower is true, this check prevents the message from being sent.
[How]
Remove the check that compares new value with what is stored in dc_context.
This check is not necessary as dcn1_update_clocks already checks if the value
is different from the current dcf_dp value.
