If anyone has any objections, please let me know. ------------------ [ Upstream commit e594a5e349ddbfdaca1951bb3f8d72f3f1660d73 ] When unloading the ast driver, a warning message is printed by drm_mode_config_cleanup() because a reference is still held to one of the drm_connector structs. Correct this by calling drm_crtc_force_disable_all() in ast_fbdev_destroy().
