Subject: USB: io_ti: fix sysfs-attribute creation
From: Johan Hovold <[email protected]>
commit 5d8c61bc283826827e1f06816c146bfc507d3834 upstream.
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.
