commit 0471bb479af03874b09350fcfe51d3743a5608de upstream.
Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features.
One of them is the support of PM listener events introduced by commit f8c9dfbd875b ("mptcp: add pm listener events").
It is possible to look for "mptcp_event_pm_listener" in kallsyms to know in advance if the kernel supports this feature.
