Hi Harald,
Sorry for the slow response.

Please use input_dev->dev.parent instead of cdev as it is going away.

Please use input_set_drvdata() instead of accessing private directly.

Add neo1973kbd->input = NULL here, otherwise we'll end up doing
input_free_device after input_unregister_device which is no good
(unregister will free the device if it is the last reference).

Same here, input_free_device() is harmful here.
