Subject: [PATCH v4 3/6] tools: mkfwumdata: Improve error message specificity
Date: Mon, 23 Feb 2026 14:18:37 +0100 [thread overview]
Message-ID: <20260223-feature_fwumdata-v4-3-680ea4ad6ce6@bootlin.com> (raw)
In-Reply-To: <20260223-feature_fwumdata-v4-0-680ea4ad6ce6@bootlin.com>
Replace the generic error message with a more informative one.
This helps users quickly understand the correct command-line argument
format when the tool reports an error.
