Yes, but I thought I'd keep it consistent with the other member. AFAIK,
they're one and the same on all relevant arches. I actually think
spelling it u16 for both members would make sense (for the code because
it explicitly is meant to hold two bytes), but again I think that's
better done as a trivial follow-up patch, if we really want to change this.
