Subject: drm/amd/display: Fix set scaling doesn's work
From: hongao <hongao@xxxxxxxxxxxxx>
commit 040625ab82ce6dca7772cb3867fe5c9eb279a344 upstream.
[Why]
Setting scaling does not correctly update CRTC state. As a result
dc stream state's src (composition area) && dest (addressable area)
was not calculated as expected. This causes set scaling doesn's work.
[How]
Correctly update CRTC state when setting scaling property.
