If anyone has any objections, please let me know. ------------------ From: Leo (Sunpeng) Li commit e11d41472a50742c16d53c968e143fb498fa482f upstream. [Why] The DRM mode's HDMI picture aspect ratio field was never saved in dc_stream's timing struct. This causes us to mistake a new stream to have the same timings as the old, even though the user has requested a different aspect ratio. [How] Save DRM's aspect ratio field within dc_stream's timing struct.
