The returned id will be INT_MAX, but idr.h uses unsigned int:

int ida_alloc_range(struct ida *, unsigned int min, unsigned int max, gfp_t);

If there's some reason to limit max id we can do it, otherwise it's just
a don't care flag.

Please clarify if I'm not following what you are suggesting :)

Regards,

Tony
