Subject: [PATCH] thermal: core: Replace sprintf in thermal_bind_cdev_to_trip
Date: Mon, 23 Feb 2026 08:32:45 +0100 [thread overview]
Message-ID: <20260223073245.321298-2-thorsten.blum@linux.dev> (raw)
Replace unbounded sprintf() with the safer snprintf(). While the
current code works correctly, snprintf() is safer and follows secure
coding best practices. No functional changes.
