Uwe Kleine-König e890591413 siox: don't create a thread without starting it ... When a siox master device is registered a kthread is created that is only started when triggered by userspace. So this thread might be in TASK_UNINTERRUPTIBLE state for long and trigger a warning [ 241.130465] INFO: task siox-0:626 blocked for more than 120 seconds. with the respective debug settings enabled. It might be right to put an unstarted thread to TASK_IDLE (in kernel/kthread.c:kthread()) instead, but independant of this discussion it is cleaner for siox_master_register() to start the thread immediately. The effect is that it enters its own waiting state and then stays in state TASK_IDLE which doesn't trigger the above warning. As siox_poll_thread() uses some variables of the device the initialisation of these is moved before thread creation.
