From 029d727b4f5d7c82f78e0395a0d220271c2f92b8 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Thu, 16 Aug 2018 14:42:13 -0500 Subject: fpga: dfl: fme: fix return value check in in pr_mgmt_init() In case of error, the function dfl_fme_create_region() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
