This patch removes BUG_ON in ir_raw_event_thread which IMO is a over-kill, and this kills the ir_raw_event_thread too. With a bit of additional logic in this patch, we nomore need to kill this thread. Other disadvantage of having a BUG-ON is, wake_up_process(dev->raw->thread) called on dead thread via ir_raw_event_handle will result in total lockup in SMP system. Advantage of this patch is ir-raw event thread is left in a usable state even if the fifo does not have enough bytes. This patch sets the thread into TASK_INTERRUPTIBLE if raw-fifo has less then sizeof(struct ir_raw_event) bytes. Signed-off-by:
