USB: serial: digi_acceleport: fix broken rx after throttle
In the Linux kernel, the following vulnerability has been resolved: USB: serial: digi_acceleport: fix broken rx after throttle If the port is closed while throttled, the read urb is never resubmitted and the port will not receive any further data until the device is reconnected (or the driver is rebound). Clear the throttle flags and submit the urb if needed when opening the port.
