Subject: edid-decode: Do not print the raw display use case value
Author:  Sebastian Wick <sebastian.w...@redhat.com>
Date:    Sun Jun 16 12:16:39 2024 +0200

If it cannot be converted to readable string, a failure is added which
includes the raw value. In libdisplay-info we do not keep around the raw
value which makes it hard to replicate the edid-decode output.
