Yep, otherwise we'll have yet more code to review rather than one

I work on the principle that if something can be expressed numerically,
that's always better than expressing it with code.

Having a hook allows for more flexibility (for example having special
alignment requirements depending on the device or something like that),
but I don't need this flexibility for the specific case I'm interested
in. So as you suggest, let's not over-engineer this, and use numerical
values. I'll rework my patch according to this suggestion.

Thanks,

Thomas
