From fcf7d2141f4a363a4a8454c4a0f26bb69e766c5f Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Tue, 20 Apr 2010 10:37:57 -0400 Subject: [PATCH] USB: OHCI: don't look at the root hub to get the number of ports 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.
