commit a75b49db6529b2af049eafd938fae888451c3685 upstream.
Make sure to destroy the workqueue also in case of early errors during bind (e.g. a subcomponent failing to bind).
Since commit c3b790ea07a1 ("drm: Manage drm_mode_config_init with drmm_") the mode config will be freed when the drm device is released also when using the legacy interface, but add an explicit cleanup for consistency and to facilitate backporting.
