From 374cb8610ac15737acb65ca0293c21dc2205662b Mon Sep 17 00:00:00 2001 From: Doug Ledford Date: Tue, 25 Apr 2017 14:00:59 -0400 Subject: [PATCH] RDMA/bnxt_re: Use IS_ERR_OR_NULL where appropriate Constructs such as if (ptr && !IS_ERR(ptr)) can be shorted to just !IS_ERR_OR_NULL(ptr) instead. Make substitutions in the bnxt_re driver where appropriate.
