Subject: [PATCH v3 04/17] rv: Remove trailing whitespace from tracepoint string
Date: Tue, 15 Jul 2025 09:14:21 +0200	[thread overview]
Message-ID: <20250715071434.22508-5-gmonaco@redhat.com> (raw)
In-Reply-To: <20250715071434.22508-1-gmonaco@redhat.com>

RV event tracepoints print a line with the format:
    "event_xyz: S0 x event -> S1 "
    "event_xyz: S1 x event -> S0 (final)"

While printing an event leading to a non-final state, the line
has a trailing white space (visible above before the closing ").

Adapt the format string not to print the trailing whitespace if we are
not printing "(final)".
