From 30e9672ac37f7b8b9e1379d25882798d8e76a96f Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 12 Oct 2022 18:00:59 +0300 Subject: [PATCH] net: marvell: prestera: fix a couple NULL vs IS_ERR() checks The __prestera_nexthop_group_create() function returns NULL on error and the prestera_nexthop_group_get() returns error pointers. Fix these two checks.
