The rcu_head pointer passed to taprio_free_sched_cb is never NULL. That means that the result of container_of() operations on it is also never NULL, even though rcu_head is the first element of the structure embedding it. On top of that, it is misleading to perform a NULL check on the result of container_of() because the position of the contained element could change, which would make the check invalid. Remove the unnecessary NULL check. This change was made automatically with the following Coccinelle script. @@ type t; identifier v; statement s; @@ <+...
