Subject: [PATCH v2 5/5] export_report: Use new version info format
Date: Sat, 18 Nov 2023 02:54:46 +0000	[thread overview]
Message-ID: <20231118025748.2778044-6-mmaurer@google.com> (raw)
In-Reply-To: <20231118025748.2778044-1-mmaurer@google.com>

The new version info format has a superset of symbols in the old format.
Since this is a tool for in-tree modules, we don't need to parse the old
one with this tool any longer.
