From 960526d5970f80497ae500441adc2554c72dcf7e Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Thu, 22 Mar 2018 02:09:39 +0000 Subject: [PATCH] staging: mt7621-eth: fix return value check in mtk_probe() In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
