Subject: [PATCH 2/5] input: twl6040-vibra: add handler to unregister input if module is removed

commit 1f9e1470ab34 ("Input: twl6040-vibra - use devm functions")

converted everything to devm but we still need to call
input_unregister_device(info->input_dev)

Solution: add back twl6040_vibra_remove to call input_unregister_device
