From 12c3da346eb81b6a281031f62eda3bca993dff5a Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Wed, 23 Nov 2005 12:09:52 -0500 Subject: [PATCH] USB: Store port number in usb_device This patch (as610) adds a field to struct usb_device to store the device's port number. This allows us to remove several loops in the hub driver (searching for a particular device among all the entries in the parent's array of children).
