[40/53] USB: ark3116 initialisation fix

[Greg KH]

3.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bart Hartgers <bart.hartgers@xxxxxxxxx>

commit 583182ba5f02c8c9be82ea550f2051eaec15b975 upstream.

This patch for the usb serial ark3116 driver fixes an initialisation
ordering bug that gets triggered on hotplug when using at least recent
debian/ubuntu userspace. Without it, ark3116 serial cables don't work.
