This function actually operates on u32 yet its paramteres were declared
as u16, causing integer truncation upon calling.
Note in patch context that ADDIP_SERIAL_SIGN_BIT is already 32 bits.

This issue exists since before git import, so I can't put a Fixes tag.
Also, that said, probably not worth queueing it to stable.
