At the moment, writes to BAR registers that aren't 4 byte aligned are
ignored. So, there's no overflow yet. Nevertheless, if this behaviour
changes in the future, it could unintentionally, introduce a buffer
overflow. Additionally, some compiler or tools will detect this
potential overflow and complain about it.
