Thanks for the patch. but musb_stop() is called in the .udc_stop() and host .stop() hooks, which can stop (and restart) at any time by the udc or host core, not really during unregister. musb_platform_init() is not called in .udc_start() and .start() hooks, so we shouldn't add musb_platform_exit() in musb_stop().
