Oliver Neukum 1426bd2c9f USB: cdc-wdm: fix race between write and disconnect due to flag abuse ... In case of a disconnect an ongoing flush() has to be made fail. Nevertheless we cannot be sure that any pending URB has already finished, so although they will never succeed, they still must not be touched. The clean solution for this is to check for WDM_IN_USE and WDM_DISCONNECTED in flush(). There is no point in ever clearing WDM_IN_USE, as no further writes make sense. The issue is as old as the driver.
