If anyone has any objections, please let me know. ------------------ From: Osama Abdelkader commit 26f6654a9a60eb4d241f42a0ec85412e8821480b upstream. 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().
