3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Hutchings <b...@decadent.org.uk>
commit 4b961180ef275035b1538317ffd0e21e80e63e77 upstream.
ite_dev::rdev is currently initialised in ite_probe() after
rc_register_device() returns. If a newly registered device is opened
quickly enough, we may enable interrupts and try to use ite_dev::rdev
before it has been initialised. Move it up to the earliest point we
can, right after calling rc_allocate_device().
