From eb43efd062d10bacdf6b50df0e300a7049474e51 Mon Sep 17 00:00:00 2001 From: Thorsten Blum Date: Tue, 15 Apr 2025 09:24:33 +0200 Subject: [PATCH] m68k: Replace memcpy() + manual NUL-termination with strscpy() Use strscpy() to safely copy the command-line string instead of memcpy() followed by a manual NUL-termination. The source string is also NUL-terminated and meets the __must_be_cstr() requirement of strscpy(). No functional changes intended.
