From: Alan Stern <stern@xxxxxxxxxxxxxxxxxxx>
This patch (as1371) fixes a small bug in ohci-hcd. The HCD already
knows how many ports the controller has; there's no need to go looking
at the root hub's usb_device structure to find out. Especially since
the root hub's maxchild value is set correctly only while the root hub
is bound to the hub driver.
