From c1f1f16c4de407fa1924e3aa4ddbc567c0a86095 Mon Sep 17 00:00:00 2001 From: Tom Rix Date: Mon, 7 Sep 2020 11:04:38 -0700 Subject: net: sched: skip an unnecessay check Reviewing the error handling in tcf_action_init_1() most of the early handling uses err_out: if (cookie) { kfree(cookie->data); kfree(cookie); } before cookie could ever be set. So skip the unnecessay check. Signed-off-by: Tom Rix Signed-off-by: David S.
