Re: [PATCH 1/7] USB: cdc-acm: fix double free on probe failure

If tty-device registration fails the driver copy of any Country Selection functional descriptor would end up being freed twice; first explicitly in the error path and then again in the tty-port destructor.

Drop the first erroneous free that was left when fixing a tty-port resource leak.
