From c62a693d8d6b052e562bd471df59b8ec05da3fbd Mon Sep 17 00:00:00 2001 From: Thorsten Blum Date: Mon, 4 May 2026 10:18:05 +0200 Subject: [PATCH] dio: Replace deprecated strcpy with strscpy in dio_init strcpy() has been deprecated [1] because it performs no bounds checking on the destination buffer, which can lead to buffer overflows. While the current code works correctly, replace strcpy() with the safer strscpy() to follow secure coding best practices.
