Subject: [PATCH net,v2 0/3] fix null pointer access issue in qdisc

These three patches fix the same type of problem. Set the default qdisc,
and then construct an init failure scenario when the dev qdisc is
configured on mqprio to trigger the reset process. NULL pointer access
may occur during the reset process.

---
v2: for fq_codel, revert the patch

Zhengchao Shao (3):
  net: sched: cake: fix null pointer access issue when cake_init() fails
  Revert "net: sched: fq_codel: remove redundant resource cleanup in
    fq_codel_init()"
  net: sched: sfb: fix null pointer access issue when sfb_init() fails
