Subject: [PATCH] drm/exynos: remove bridge when component_add fails
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use devm_drm_bridge_add() so the bridge is released if probe fails after
registration, and drop the manual drm_bridge_remove() in remove().

Check the return value of devm_drm_bridge_add().
