[PATCH 4.15 03/52] selftests/x86/entry_from_vm86: Exit with 1 if we fail

From: Greg Kroah-Hartman
Date: Mon Mar 19 2018 - 14:32:06 EST


4.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Andy Lutomirski <luto@xxxxxxxxxx>

commit 327d53d005ca47b10eae940616ed11c569f75a9b upstream.

Fix a logic error that caused the test to exit with 0 even if test
cases failed.
