Vineeth Vijayan fe990b7bf6 s390/cio: verify the driver availability for path_event call ... commit dd9cb842fa upstream. If no driver is attached to a device or the driver does not provide the path_event function, an FCES path-event on this device could end up in a kernel-panic. Verify the driver availability before the path_event function call.
