From 5d8c61bc283826827e1f06816c146bfc507d3834 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 18 Oct 2012 11:43:28 +0200 Subject: [PATCH] USB: io_ti: fix sysfs-attribute creation Make sure port data is initialised before creating sysfs attributes to avoid a race. A recent patch ("USB: io_ti: fix port-data memory leak") got the sysfs-attribute creation and port-data initialisation ordering wrong.
