[PATCH] usbcore: Fix handling of sysfs strings and other attributes

Browse Source 
This patch (as592) makes a few small improvements to the way device
strings are handled, and it fixes some bugs in a couple of other sysfs
attribute routines.  (Look at show_configuration_string() to see what I
mean.)
