Tong Zhang 01e03a6618 drm/ast: fix memory leak when unload the driver ... [ Upstream commit dc739820ff ] a connector is leaked upon module unload, it seems that we should do similar to sample driver as suggested in drm_drv.c. Adding drm_atomic_helper_shutdown() in ast_pci_remove to prevent leaking.
