From 4f62efe67f077db17dad03a1d4c9665000a3eb45 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Mon, 24 Oct 2005 16:24:14 -0400 Subject: [PATCH] usbcore: Fix handling of sysfs strings and other attributes 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.)
