When unbinding the firmware device we need to make sure it has no consumers left. Otherwise we'd leave them with a firmware handle pointing at freed memory. Keep a reference count of all consumers and make sure they all finished unbinding before we do.
Wait, if it's a device, why do we need all these? get_device() / put_device() along with module_get() / module_put() should be sufficient, no? -- With Best Regards, Andy Shevchenko
