[PATCH v2 0/2] sched: Return NULL when entity isn't a task

[Yajun Deng <yajun.deng@linux.dev>]

If the entity isn't a task, return the task struct is meaningless.
Return NULL when entity isn't a task that makes the code more concise.

v1 -> v2: 
fix 'struct rt_rq' no member named 'highest_prio'.

Yajun Deng (2):
  sched/fair: Return NULL when entity isn't a task in task_of()
  sched/rt: Return NULL when rt entity isn't a task in rt_task_of()
