There are some functions call create_singlethread_workqueue() without
checking ret value, and the NULL workqueue_struct pointer may causes
null-ptr-deref. Will be fixed by this patch.

lan966x_stats_init() calls create_singlethread_workqueue() and not
checked the ret value, which may return NULL. And a null-ptr-deref may
happen:

lan966x_stats_init()
    create_singlethread_workqueue() # failed, lan966x->stats_queue 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.

* [PATCH 2/2] net: microchip: sparx5: Fix potential null-ptr-deref in sparx_stats_init() and sparx5_start()

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

sparx_stats_init()
    create_singlethread_workqueue() # failed, sparx5->stats_queue 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. So as
sparx5_start().
