usbcore: add configuration_string to attribute group
This patch (as737b) does a very small cleanup of core/sysfs.c by adding the configuration_string attribute file to the existing attribute group instead of treating it separately. It doesn't need this separate treatment because unlike the other device string attributes, it changes along with the active configuration. The patch also fixes a simple typo (which, oddly enough, doesn't seem to bother the compiler). Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
