Hi, this series fixes hub_configure() error handling that causes hub->ports[i] NULL pointer dereferences that were previously reported at: "[PATCH] Prevent USB hub remove oops" http://marc.info/?l=linux-kernel&m=136189072520909&w=4 https://bugzilla.redhat.com/show_bug.cgi?id=926907 This bug still exists in 3.11-rc6 and I've got an Oops during startup caused by hub->ports[i] dereference in hub_quiesce(). The first patch implements what Alan Stern suggested in the "[PATCH] Prevent USB hub remove oops" thread: "All of these problems can be fixed in hub_configure by setting hub->maxchild to the total number of allocated ports (or 0 if hub_ports can't be allocated)." http://marc.info/?l=linux-usb&m=136189486922963&w=4 The second patch uses slightly different approach because some users ignore hub->maxchild and use hub->descriptor->bNbrPorts.
