This patch (as950) fixes a bug in the cdc-acm driver. It doesn't keep
track of which interface (control or data) the sysfs attributes get
registered for, and as a result, during disconnect it will sometimes
attempt to remove the attributes from the wrong interface. The
left-over attributes can cause a crash later on, particularly if the driver
module has been unloaded.
