[PATCH v8 2/8] drm/bridge: analogix_dp: Fix connector and encoder cleanup

From: Thierry Escande
Date: Wed Jan 10 2018 - 11:25:38 EST


From: Jeffy Chen <jeffy.chen@xxxxxxxxxxxxxx>

Since we are initing connector in the core driver and encoder in the
plat driver, let's clean them up in the right places.
