From a4d44b6bfa193d1b25d8fb72f6566c4556cad0d5 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Sun, 19 Aug 2012 19:32:27 -0300 Subject: rc: ite-cir: Initialise ite_dev::rdev earlier 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().
