From: Fatemeh Darbehani <fatemeh.darbehani@xxxxxxx> [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.
