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().
Fixes: 52c0fdb25c7c9 ("drm/i915: Replace global breadcrumbs ...")
