From 583182ba5f02c8c9be82ea550f2051eaec15b975 Mon Sep 17 00:00:00 2001 From: Bart Hartgers Date: Wed, 26 Oct 2011 13:29:42 +0200 Subject: [PATCH] USB: ark3116 initialisation fix 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.
