From 8f4caef8d5401b42c6367d46c23da5e0e8111516 Mon Sep 17 00:00:00 2001 From: Zhihao Cheng <chengzhihao1@huawei.com> Date: Tue, 1 Jun 2021 09:19:35 +0000 Subject: [PATCH] drm/i915/selftests: Fix return value check in live_breadcrumbs_smoketest() In case of error, the function live_context() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
