Subject[028/117] USB: OHCI: dont look at the root hub to get the number of ports
2.6.33-stable review patch.  If anyone has any objections, please let us know.


From: Alan Stern <>

commit fcf7d2141f4a363a4a8454c4a0f26bb69e766c5f upstream.

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.
