From e31abf76f4d4d3202ca16b9668b11178df23d473 Mon Sep 17 00:00:00 2001 From: "weiyongjun (A)" Date: Thu, 7 Jun 2018 01:47:41 +0000 Subject: IB/mlx5: Fix return value check in flow_counters_set_data() In case of error, the function mlx5_fc_create() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
