Help for warning msg in OPatch

I applied Oracle PSU 11.2.0.2.12 (17082367) on my Oracle 11.2.0.2 on Linux x86-64. At the end, I received a warning msg. Could someone advise if it's OK to leave it as is or I need to fix it. If I need to do something, plese guide me. I have no idea what I need to do. Thanks in advance.
