Subject: [PATCH] drm/amdgpu: Fix connector atomic_check compilation fail
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

I missed amdgpu in my connnector_helper_funcs->atomic_check conversion,
which is understandably causing compilation failures.

Fixes: 6f3b62781bbd ("drm: Convert connector_helper_funcs->atomic_check to accept drm_atomic_state")
