[PATCH] fbdev: macfb: Replace deprecated strcpy with strscpy

flat view
STALE220d

From: Thorsten Blum <hidden>
Date: 2026-03-05 10:40:02
Also in: dri-devel, lkml
Subsystem: framebuffer layer, the rest · Maintainers: Helge Deller, Linus Torvalds 

strcpy() has been deprecated [1] because it performs no bounds checking
on the destination buffer, which can lead to buffer overflows. Replace
it with the safer strscpy().  No functional changes.
