Subject: [for-linus][PATCH 1/3] tracing/synthetic: Print out u64 values properly
Date: Tue, 12 Sep 2023 14:22:14 -0400	[thread overview]
Message-ID: <20230912182240.156094298@goodmis.org> (raw)
In-Reply-To: 20230912182213.795801173@goodmis.org

From: Tero Kristo <tero.kristo@linux.intel.com>

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.

Fixes: ddeea494a16f ("tracing/synthetic: Use union instead of casts")
