I doubt whether this falls to the category you are referring.
This function returns number of resources setup, please see
similar for irq too, there it can be 2 also, success or failure
is not sufficient for the other, and with this we have both
functions returning values similar way.

It is to stress the fact that flag user is passing need not be
same as irq bit (here both have same value), this kind of an
arrangement would be required later if waitpin interrupt also
has to be handled, do you still prefer removing it now ?
