It also tries to bind the various components of the display pipeline, some of which may add additional drm objects. This patch adds proper cleanup functions in the error path of the master bind function. This requires the patch "drm/sun4i: Move drm_mode_config_cleanup call to main driver", which splits out drm_mode_config_cleanup from sun4i_framebuffer_free so we can call it separately.
