Date: Fri, 21 Feb 2020 08:40:10 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Wei Yongjun <weiyongjun1@...wei.com>, Borislav Petkov <bp@...e.de>, Sasha Levin <sashal@...nel.org> Subject: [PATCH 5.5 285/399] EDAC/sifive: Fix return value check in ecc_register() From: Wei Yongjun <weiyongjun1@...wei.com> [ Upstream commit 6cd18453b68942913fd3b1913b707646e544c2ac ] In case of error, the function edac_device_alloc_ctl_info() returns a NULL pointer, not ERR_PTR(). Replace the IS_ERR() test in the return value check with a NULL test.
