Johan Hovold b5aedddb62 USB: cdc-acm: fix double free on probe failure
commit 7180495cb3d0e2a2860d282a468b4146c21da78f upstream.

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.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
