Subject: tracing/synthetic: Print out u64 values properly
From: Tero Kristo <tero.kristo@xxxxxxxxxxxxxxx>
commit 62663b849662c1a5126b6274d91671b90566ef13 upstream.
The synth traces incorrectly print pointer to the synthetic event values
instead of the actual value when using u64 type. Fix by addressing the
contents of the union properly.
