Subject: [PATCH] staging: greybus: Replace strncpy with strscpy
Date: Sun, 2 Aug 2026 21:26:20 -0400 [thread overview]
Message-ID: <20260803012620.5503-1-noahtechoueyres@gmail.com> (raw)
Replace deprecated strncpy() with strscpy() to improve string
handling safety. strscpy() guarantees null-termination and is
the preferred function per the kernel string handling guidelines.
