You have a hunk in patch 1/3 changing the argument being passed to this
function to u16 but you're changing the actual function right here, in
3/3, which is strange and easy to puzzle a potential reviewer.

As a rule of thumb: always do your changes to the functions and their callsites
in one patch so that they belong together and can be reviewed easily.

Thanks.
