Revision 306381aec7c2b5a658eebca008c8a1b666536cba authored by Cong Wang on 09 July 2020, 03:13:59 UTC, committed by David S. Miller on 09 July 2020, 19:31:28 UTC
When tcf_block_get() fails inside atm_tc_init(),
atm_tc_put() is called to release the qdisc p->link.q.
But the flow->ref prevents it to do so, as the flow->ref
is still zero.
Fix this by moving the p->link.ref initialization before
tcf_block_get().
Fixes: 6529eaba33f0 ("net: sched: introduce tcf block infractructure")
