From 494f5063b86cd6e972cb41a27e083c9a3664319d Mon Sep 17 00:00:00 2001 From: Zhengchao Shao Date: Fri, 2 Sep 2022 16:34:29 +0800 Subject: net: sched: fq_codel: remove redundant resource cleanup in fq_codel_init() If fq_codel_init() fails, qdisc_create() invokes fq_codel_destroy() to clear resources. Therefore, remove redundant resource cleanup in fq_codel_init(). Signed-off-by: Zhengchao Shao Signed-off-by: David S.
