USB: ark3116 initialisation fix
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. Signed-off-by: Bart Hartgers <bart.hartgers@gmail.com> Tested-by: law_ence.dev@ntlworld.com Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
