USB: serial: fix potential use-after-free after failed probe
Fix return value in probe error path, which could end up returning success (0) on errors. This could in turn lead to use-after-free or double free (e.g. in port_remove) when the port device is removed. Fixes: c706ebdfc895 ("USB: usb-serial: call port_probe and port_remove at the right times") Cc: stable <stable@vger.kernel.org> # v2.6.31 Signed-off-by: Johan Hovold <johan@kernel.org> Acked-by: Greg Kroah-Hartman <greg@kroah.com>
