[PATCH 2/2] drm/amd/display: Fix coding error in connector atomic check

[mikita.lipski at amd.com]

From: Mikita Lipski <mikita.lipski at amd.com>

[why]
For MST connector atomic check we have to check a new CRTC state
instead of an old one, when checking if CRTC is disabled to
release VCPI slots allocated.
