Subject: [PATCH] crypto: hifn_795x - Replace snprintf("%s") with strscpy
Date: Tue, 24 Mar 2026 12:27:05 +0100	[thread overview]
Message-ID: <20260324112703.94917-3-thorsten.blum@linux.dev> (raw)

Replace snprintf("%s", ...) with the faster and more direct strscpy().
Check if the return value is less than 0 to detect string truncation.
