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.

This is problematic for uniprocessor configurations, where the affinity mask should be constant, as it is known at compile time. Add and use a setter for the affinity mask, following the pattern of irq_data_update_effective_affinity. This allows the getter function to return a const cpumask pointer.
