USB: EHCI: simplify remainder computations This patch (as1406) adds a micro-optimization to ehci-hcd's scheduling code. Instead of computing remainders with respect to the schedule length, use bitwise-and (which is quicker). We know that the schedule length will always be a power of two, but the compiler doesn't have this information.
