[PATCH v2 24/85] USB: serial: fix generic disconnect implementation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is no need for the generic disconnect callback to stop the read
and write urbs a second time as this has already been taken care of by
close (which is called from hangup as part of disconnect).
