Subject: [PATCHv2 0/2] sched/deadline: Fix potential race in dl_add_task_root_domain()

These two patches address the issue reported by Juri [1] (thanks!).

The first removes an unnecessary comment, the second is the actual fix.

@Tejun, while these could be squashed together, I kept them separate to
maintain the one-patch-one-purpose rule. let me know if you'd like me to
resend these in a different format, or feel free to adjust as needed.
