Oliver Neukum 19f955ad94 usb: cdc-wdm: close race between read and workqueue ... commit 339f83612f upstream. wdm_read() cannot race with itself. However, in service_outstanding_interrupt() it can race with the workqueue, which can be triggered by error handling. Hence we need to make sure that the WDM_RESPONDING flag is not just only set but tested.
