Subject: drm/radeon: fix panel scaling with eDP and LVDS bridges
From: Alex Deucher <[email protected]>
commit 855f5f1d882a34e4e9dd27b299737cd3508a5624 upstream.
We were using the wrong set_properly callback so we always
ended up with Full scaling even if something else (Center or
Full aspect) was selected.
