drm/radeon/kms: rework scaler handling
Keep requested scaler type in radeon_encoder and the actual scaler type used in radeon_crtc. This prevents us from enabling the scaler when it's not required (i.e., the requested mode is the native mode). Also, always set the adjusted mode equal to the native mode for lvds. Should fix: https://bugzilla.redhat.com/show_bug.cgi?id=522271 Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Acked-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
