I don't think this change really improves things.  For standalone comparisons I agree
that having the constant on the RHS is best, but here it is like a normal mathematical
expression "X <= type < Y" which I think is reasonable to keep even if checkpatch.pl
complains a bit.

That said, I don't have strong feelings about this and Greg can apply it or not as he
sees fit.  I guess the benefit of applying it is that it stops anyone else from sending
the same patch in the future...

Cheers, Andreas
