not needed:

 * devm_input_allocate_device - allocate managed input device
 * @dev: device owning the input device being created
 *
 * Returns prepared struct input_dev or %NULL.
 *
 * Managed input devices do not need to be explicitly unregistered or
 * freed as it will be done automatically when owner device unbinds from
 * its driver (or binding fails). [...]
