Ack to both. This seems like a fine line to me as the fields are not
contributing to anything except confusion. Specifically hw_mdp which is
never initialized and may accidentally be used without realizing that
it'll stay NULL, but that is again up to the developer using the field
at that point.
Feel free to drop them while applying, or should I reword the message to
at least still link these commits to mention the origin of the unused
fields?
