Shang XiaoJing 67c98fec87 parisc: led: Fix potential null-ptr-deref in start_task() 
commit 41f563ab3c upstream.

start_task() calls create_singlethread_workqueue() and not checked the
ret value, which may return NULL. And a null-ptr-deref may happen:

start_task()
    create_singlethread_workqueue() # failed, led_wq is NULL
    queue_delayed_work()
        queue_delayed_work_on()
            __queue_delayed_work()  # warning here, but continue
                __queue_work()      # access wq->flags, null-ptr-deref

Check the ret value and return -ENOMEM if it is NULL.

Fixes: 3499495205 ("[PARISC] Use work queue in LED/LCD driver instead of tasklet.")
