From c68febfd68e0f01d90da15bd10e94b42544f0f68 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 3 Jan 2018 07:33:35 +0000 Subject: PCI: dwc: artpec6: Fix return value check in artpec6_add_pcie_ep() In case of error, the function devm_ioremap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.
