Please test the attached patch, following instructions at <http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-official> Ben. -- Ben Hutchings Sturgeon's Law: Ninety percent of everything is crap.
From ac6ba83515001f68722f5846f2a95ee42377bd71 Mon Sep 17 00:00:00 2001 From: Ben Hutchings <b...@decadent.org.uk> Date: Sun, 12 Aug 2012 22:47:41 +0100 Subject: [PATCH] [media] rc: ite-cir: Initialise ite_dev::rdev earlier 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().
