Subject: [for-next][PATCH 09/12] selftests/ftrace: Change synthetic event name for
 inter-event-combined test

From: Tom Zanussi <zanussi@...nel.org>

This test uses waking+wakeup_latency as an event name, which doesn't
make sense since it includes an operator.  Illegal names are now
detected by the synthetic event command parsing, which causes this
test to fail.  Change the name to 'waking_plus_wakeup_latency' to
prevent this.
